   More detail

   Die Luft means “the air.” Luft is a feminine noun, so its singular definite article is die. The same article form can have other grammatical functions, but here it marks a singular definite noun. The noun is also useful in compounds such as Luftqualität later in the sentence. fühlt sich … an is the separable reflexive verb construction sich anfühlen, “to feel” or “to seem” in a sensory or descriptive judgment. The form fühlt is the third-person singular present form of fühlen; sich is the reflexive pronoun matching this third-person subject. In a main clause, the prefix an moves to the end: Die Luft fühlt sich schwer an. Example: Der Stoff fühlt sich weich an. — “The fabric feels soft.” heute means “today.” It places the described impression in the current day and can be moved for emphasis without changing its basic time reference. schwer means “heavy” here. With sich anfühlen, it is a predicate adjective describing how the air feels, so it has no adjective ending in this position. Its basic comparative forms are schwer — schwerer — am schwersten (“heavy” — “heavier” — “heaviest”), though the sentence uses only the base form. Example: Die Tasche fühlt sich schwer an. — “The bag feels heavy.” die Luftqualität means “air quality.” It is a feminine singular compound noun: Luft + Qualität, with the final component determining the grammatical gender. The definite article die therefore appears again. The compound names the quality or condition of the air, rather than the air as a physical substance. könnte expresses possibility: “may” or “might.” It is the third-person singular Konjunktiv II form of the modal verb können (“can; be able to”). Here it makes the assessment tentative rather than certain. The modal is followed by an infinitive at the end of its clause: könnte schlecht sein. Example: Die Straße könnte glatt sein. — “The road might be slippery.” schlecht means “poor” in this context, describing the quality of the air. It is a predicate adjective with sein, so it has no adjective ending here. In other contexts, schlecht can mean “bad,” but “poor” fits the stated air-quality meaning. sein is the infinitive “to be.” After the modal könnte, German uses the infinitive rather than a finite form: könnte … sein. The combination schlecht sein means “be poor” here, while könnte adds the possibility meaning. Together, Die Luft fühlt sich heute schwer an says that the air has a heavy-feeling quality today. und joins a second clause, die Luftqualität könnte schlecht sein, which tentatively assesses the air quality as poor. The complete meaning is: “The air feels heavy today, and air quality may be poor.”

2. Dann ist Sport im Freien vielleicht keine gute Idee.

   Outdoor exercise might not be a good idea, then.

   Dann

   then

   ist

   is

   Sport

   exercise; sport

   im Freien

   outdoors

   vielleicht

   perhaps; maybe

   keine

   no; not a

   gute

   good

   Idee

   idea

   More detail

   Dann means “then” here in the sense of “in that case”: it links this conclusion to the situation already mentioned. It can also refer to a time, but that is not the meaning in this sentence. Example: Dann gehen wir nach Hause. — “Then we’ll go home.” ist is the third-person singular present form of sein (“to be”). The subject here is Sport im Freien, so German uses singular ist. The same form can link a subject with a description or identification: Das ist eine gute Idee. — “That is a good idea.” Sport is a masculine noun meaning “sport” or “exercise.” In this sentence it refers broadly to physical exercise, not necessarily to one particular sport. German nouns are capitalized; its base form is also Sport. im Freien is a fixed expression meaning “outdoors” or “in the open air.” im is the contraction of in dem; Freien is the capitalized nominalized form of frei (“open/free”). The expression is useful as a location phrase: Wir essen im Freien. — “We eat outdoors.” vielleicht means “perhaps” or “maybe.” It marks the speaker’s conclusion as uncertain rather than definite. Example: Vielleicht regnet es. — “Maybe it will rain.” keine is the negative determiner used with the feminine singular noun Idee here. It means “no” or, in this predicate phrase, “not a.” It is not by itself a statement of a numeric quantity. Compare eine gute Idee — “a good idea” and keine gute Idee — “not a good idea.” gute is the feminine singular nominative form of the adjective gut (“good”). It describes Idee; the ending -e appears in keine gute Idee because this noun phrase is a nominative predicate after sein and follows the determiner keine. Other forms include gut in ein guter Plan and guten in einen guten Plan. Idee is a feminine noun meaning “idea.” Its plural is Ideen. In this sentence, the noun phrase keine gute Idee is the predicate describing Sport im Freien. The structure is Dann ist [subject] vielleicht [predicate]: Dann occupies the first position, and the finite verb ist comes second, as is normal in a German main clause. The subject is Sport im Freien (“outdoor exercise”), while keine gute Idee says that this activity is not a good idea. Vielleicht softens that judgment, so the complete meaning is: “Outdoor exercise might not be a good idea, then.”

3. Ich hatte vor, im Park zu laufen.

   I was planning to run in the park.

   Ich

   I

   hatte vor

   was planning to

   Park

   park

   laufen

   run

   More detail

   Ich is the first-person singular pronoun: it refers to the speaker. It is the nominative form used for the subject of the clause. For example, Ich lerne Deutsch. means “I am learning German.” hatte vor is the past-tense form of the construction vorhaben, meaning “to plan” or “to intend.” Here, hatte is the first- and third-person singular Präteritum form of haben; the element vor belongs with haben, rather than meaning “in front of” in this construction. With a following infinitive, the reusable pattern is Ich hatte vor, ... zu + infinitive (“I planned/intended to ...”). For example, Sie hatte vor, früh aufzustehen. means “She planned to get up early.” Park is the noun “park.” In im Park, im is the contraction of in dem; the location reading uses the dative form after in, giving “in the park.” The noun’s base form is der Park, and its plural is die Parks. laufen is the infinitive meaning “to run” in this sentence, as fixed by the translation. The infinitive is used after zu, producing zu laufen; zu marks the infinitive construction and is not part of the quoted lexical form laufen. Depending on context, laufen can also mean “to walk” or “to function/run” for something such as a machine, so the surrounding context determines the intended sense. For example, Ich versuche, jeden Morgen zu laufen. means “I try to run every morning.” Together, Ich hatte vor presents the speaker’s plan in the past, and im Park zu laufen states the planned activity and its location. The complete utterance therefore means “I was planning to run in the park.”

4. Wenn dich die Luftverschmutzung stört, mach stattdessen drinnen Sport.

   If pollution bothers you, choose an indoor workout instead.

   Wenn

   if

   dich

   you

   die Luftverschmutzung

   the air pollution

   stört

   bothers

   mach

   do

   stattdessen

   instead

   drinnen

   indoors

   Sport

   exercise

   More detail

   Wenn introduces a condition: “if/when.” In this sentence it sets up the condition for the main instruction. A reusable pattern is Wenn ... , .... dich is the accusative form of the second-person singular pronoun du (“you”). Here, “you” is the person affected by the pollution; die Luftverschmutzung is the grammatical subject of stört. Compare du as subject with dich as an object: Du trainierst. — “You exercise.” Die Luft stört dich. — “The air bothers you.” die Luftverschmutzung means “the air pollution.” It is a feminine noun, so its nominative singular definite article is die. The compound combines Luft (“air”) and Verschmutzung (“pollution”), but learn the complete noun as die Luftverschmutzung. stört comes from stören, “to bother” or “to disturb.” The -t form is present tense, third-person singular, agreeing with the singular subject die Luftverschmutzung, not with dich: Die Luftverschmutzung stört dich. — “The air pollution bothers you.” In the subordinate clause introduced by Wenn, the finite verb appears at the end: Wenn dich etwas stört — “If something bothers you.” mach is the informal singular imperative of machen, “to do” or “to make.” The subject du is understood and normally omitted in this imperative. mach is therefore an instruction to one person, not a present-tense statement. The usual expression Sport machen means “to exercise” or “to do sport.” Example: Mach heute Sport! — “Exercise today!” stattdessen means “instead” and tells the listener to choose an alternative to the activity or option already under consideration. It is an adverb and does not change form. drinnen means “indoors” or “inside.” It is an adverb of place, so it does not take an ending for the person or thing involved. Example: Wir trainieren drinnen. — “We exercise indoors.” Sport means “sport” or “exercise” here. In the fixed expression Sport machen, it refers to exercising rather than to one particular sport. The noun is masculine in German (der Sport), although no article is used in this expression. Together, Wenn dich die Luftverschmutzung stört means “If the air pollution bothers you.” The subordinate clause places stört at the end. The main clause mach stattdessen drinnen Sport is an informal singular instruction: “exercise indoors instead.” The complete utterance therefore means: “If pollution bothers you, choose an indoor workout instead.”

5. Ich könnte im Fitnessstudio trainieren, obwohl es dort weniger entspannend ist als im Park.

   I could use the gym, although it feels less relaxing than the park.

   Ich könnte

   I could

   Fitnessstudio

   gym

   trainieren

   train; work out

   obwohl

   although

   weniger entspannend

   less relaxing

   Park

   park

   More detail

   Ich könnte means “I could” here: könnte is the Konjunktiv II form of können, used for a possible or conditional option. The subject is Ich (“I”). Compare Ich kann ... (“I can ...”) with Ich könnte ... (“I could ...” / “I might be able to ...”). With a modal verb, the other verb normally appears as an infinitive at the end of the clause. Fitnessstudio means “gym” or “fitness center.” Its basic form is das Fitnessstudio; after in for a stationary location, German uses the dative: im Fitnessstudio = in dem Fitnessstudio, “at/in the gym.” trainieren means “to train” or “to work out.” It is the infinitive selected by könnte: Ich könnte im Fitnessstudio trainieren = “I could work out at the gym.” The related finite form for “I train/work out” is ich trainiere. obwohl means “although” and introduces a subordinate clause. In this clause, the finite verb comes at the end: obwohl es dort weniger entspannend ist (“although it is less relaxing there”). This conjunction presents a contrast or concession; it does not cancel the possibility expressed by könnte. weniger entspannend means “less relaxing.” weniger marks a lower degree, while entspannend describes the experience or atmosphere. The comparison pattern is weniger + adjective + als: Dieser Ort ist weniger ruhig als der Park. — “This place is less quiet than the park.” Here entspannend is not a comparative inflection; the comparison is expressed with weniger. Park means “park.” The form in im Park is a dative location phrase: im is short for in dem. The noun’s basic form is der Park. In the fixed sentence, the park is the place used as the comparison point, not the place where the speaker says they could train. The main clause is Ich könnte im Fitnessstudio trainieren: the speaker presents working out at the gym as a possible option. obwohl then adds the subordinate contrast es dort weniger entspannend ist als im Park: the experience there, at the gym, is less relaxing than in the park. Together, the utterance means: “I could work out at the gym, although it feels less relaxing there than in the park.”

6. Drinnen zu trainieren ist gesünder, als schlechte Luft zu atmen.

   Training indoors is healthier than breathing poor air.

   Drinnen

   indoors

   zu trainieren

   to train; to exercise

   gesünder

   healthier

   schlechte

   bad; poor

   Luft

   air

   zu atmen

   to breathe

   More detail

   Drinnen means “indoors” and functions as an adverb of place. It describes where the training takes place. A useful contrast is draußen (“outdoors”): Ich trainiere drinnen. — “I train indoors.” zu trainieren is the infinitive of trainieren with zu, meaning “to train” or “to exercise.” Here it forms the subject of the sentence together with Drinnen: Drinnen zu trainieren — “training indoors.” With a separable verb, zu would appear inside the infinitive, but trainieren is not separable. gesünder is the comparative form of the adjective gesund (“healthy”): gesund → gesünder (“healthier”) → am gesündesten (“healthiest”). The comparative says that one option is healthier than another; it does not mean simply “healthy.” schlechte is the inflected form of schlecht (“bad” or “poor”). It describes Luft, which is feminine singular here. Because Luft appears without an article, the adjective uses the strong feminine singular ending -e: schlechte Luft. The adjective itself has the base form schlecht; Luft is its noun, not its base form. Luft means “air.” It is a feminine noun: die Luft. In this sentence, schlechte Luft means poor or bad air. Example: Frische Luft ist angenehm. — “Fresh air is pleasant.” zu atmen is the infinitive of atmen (“to breathe”) with zu. It appears in the comparison clause after als: als schlechte Luft zu atmen — “than breathing poor air.” Example: Es ist besser, frische Luft zu atmen. — “It is better to breathe fresh air.” The first part, Drinnen zu trainieren, is an infinitive clause used as the subject. ist gesünder states the comparison, and als schlechte Luft zu atmen supplies what it is being compared with. Together, the utterance means: “Training indoors is healthier than breathing poor air.”

7. Soll ich eine Maske tragen, wenn ich draußen spazieren gehen muss?

   Should I wear a mask if I need to walk outside?

   Soll ich

   should I

   eine Maske

   a mask

   tragen

   wear

   wenn

   if / when

   draußen

   outside

   spazieren gehen

   go for a walk

   muss

   must / need to

   More detail

   Soll ich asks whether the speaker ought to do something. soll is the first-person singular present form of sollen; with ich, the pattern is Soll ich ...? The modal verb is in first position because this is a yes/no question, while the main action appears later as an infinitive. Example: Soll ich warten? — “Should I wait?” eine Maske means “a mask” here. Maske is a feminine noun, and eine is its indefinite article in the accusative form required by tragen. The article signals an unspecified mask; it does not by itself state a numerical count as a fact. tragen is the infinitive meaning “to wear” or “to carry,” and here it means “wear.” It is the main action governed by sollen: Soll ich eine Maske tragen? — “Should I wear a mask?” wenn introduces a condition or time-related subordinate clause. In this sentence it has the conditional meaning “if.” A clause introduced by wenn places its finite verb at the end. Example: Wenn es regnet, bleibe ich drinnen. — “If it rains, I stay indoors.” draußen is an adverb meaning “outside” or “outdoors.” It describes where the walking takes place; it does not itself express movement toward the outside. The related location contrast is drinnen, “inside/indoors.” spazieren gehen is the fixed verb combination “to go for a walk.” spazieren contributes the walking activity, while gehen is the verb “go”; together they form a common activity expression. Example: Wir gehen am Abend spazieren. — “We go for a walk in the evening.” muss means “must” or, in this context, “need to.” It is the first-person singular present form of müssen, agreeing with the subject ich, which is stated earlier in the main question and understood in the subordinate clause. Because the clause begins with wenn, muss comes at the end: wenn ich draußen spazieren gehen muss — “if I need to go for a walk outside.” Together, Soll ich eine Maske tragen? asks whether the speaker should wear a mask. The conditional clause wenn ich draußen spazieren gehen muss specifies the situation in which that question applies. The complete meaning is: “Should I wear a mask if I need to walk outside?”

8. Eine Maske kann helfen, und die örtlichen Gesundheitshinweise könnten zusätzliche Vorsichtsmaßnahmen empfehlen.

   A mask can help, and local health advice may suggest extra precautions.

   Maske

   mask

   kann

   can

   helfen

   help

   örtlichen

   local

   Gesundheitshinweise

   health advice

   könnten

   may / could

   zusätzliche

   additional

   Vorsichtsmaßnahmen

   precautions

   empfehlen

   recommend

   More detail

   Maske means “mask” here. It is a feminine noun: die Maske is singular, while die Masken is plural. In this sentence, Eine Maske is the subject, meaning “a mask”; the indefinite article presents one nonspecific mask, without by itself asserting a numerical contrast. kann helfen combines the third-person singular present form kann of können with the infinitive helfen. können expresses ability or possibility; with Eine Maske as the singular subject, the form is kann. The infinitive remains helfen after this modal. Example: Das kann helfen. — “That can help.” helfen means “to help.” Its base form is the infinitive helfen; after a modal such as kann, German uses this infinitive rather than a finite form. The sentence says that a mask can be helpful, not that it definitely solves the problem. örtlichen means “local” in die örtlichen Gesundheitshinweise. The adjective is inflected because it modifies the plural noun Gesundheitshinweise after the definite article die; the ending -en here is carried by örtlichen, not by the noun. The base form is örtlich. Example: die örtlichen Regeln — “the local rules.” Gesundheitshinweise means “health advice” in this sentence. It is a plural compound noun: der Gesundheitshinweis is the singular and die Gesundheitshinweise the plural. The plural subject is the group that may make the recommendation. German compounds combine their parts into one noun, so this form should not be treated as two independent nouns in the sentence. könnten empfehlen expresses that the health advice may or could recommend something. könnten is the third-person plural Konjunktiv II form of können, matching plural Gesundheitshinweise; in this context it gives a tentative possibility rather than a firm prediction. The infinitive empfehlen follows the modal. Compare Sie können ... empfehlen — “They can recommend ...” — with Sie könnten ... empfehlen — “They may/could recommend ...”. zusätzliche means “additional” or “extra.” Its base form is zusätzlich; here it modifies the plural noun Vorsichtsmaßnahmen in the accusative, and the ending -e appears after no article. Example: zusätzliche Informationen — “additional information.” Vorsichtsmaßnahmen means “precautions.” It is the plural of die Vorsichtsmaßnahme. The noun is the object of empfehlen: the health advice may recommend extra precautions. Example: Wir treffen Vorsichtsmaßnahmen. — “We take precautions.” empfehlen means “to recommend.” Here it is an infinitive controlled by könnten; its subject is die örtlichen Gesundheitshinweise, and its object is zusätzliche Vorsichtsmaßnahmen. Example: Die Ärztin empfiehlt Ruhe. — “The doctor recommends rest.” Together, Eine Maske kann helfen says “A mask can help.” The coordinated clause die örtlichen Gesundheitshinweise könnten zusätzliche Vorsichtsmaßnahmen empfehlen says that local health advice may recommend extra precautions. Joined by und, the complete utterance means: “A mask can help, and local health advice may suggest extra precautions.”

9. Den Lauf zu verschieben, bis sich die Luft verbessert, scheint sicherer zu sein.

   Postponing the run until the air improves seems safer.

   Lauf

   run

   zu verschieben

   to postpone

   Luft

   air

   verbessert

   improves

   scheint … zu sein

   seems to be

   sicherer

   safer

   More detail

   Lauf means “run” here. The form is masculine: der Lauf; after verschieben it appears as the accusative den Lauf. In this sentence it refers to postponing the running activity, not necessarily to a particular race. zu verschieben is the zu-infinitive of verschieben (“to postpone” or “to move to a later time”). The infinitive lets the action function as the topic of the sentence: Den Lauf zu verschieben = “postponing the run.” A useful finite contrast is ich verschiebe den Lauf = “I postpone the run.” Luft means “air.” The noun is feminine: die Luft; here die is required by the definite noun phrase die Luft. The phrase sich die Luft verbessert means “the air improves.” verbessert is the third-person singular present form of verbessern, “to improve” or “to make better.” Here it is used with the reflexive pronoun sich, so sich verbessern means “to improve” in the sense of becoming better: Die Luft verbessert sich = “The air improves.” The ending -t marks the third-person singular present form in this clause. scheint is the third-person singular present form of scheinen, “to seem.” The construction scheint ... zu sein means “seems to be.” The subject is the whole infinitive phrase Den Lauf zu verschieben, so the sentence literally presents “postponing the run” as what seems safer. In German, the zu-infinitive can be separated from its governing verb by material inside the clause: scheint sicherer zu sein. zu sein is the zu-infinitive of sein, “to be.” Together with scheint, it completes the pattern scheinen, ... zu sein (“to seem to be”); zu belongs to sein, not to the adjective sicherer. sicherer is the comparative form of sicher, “safe” or “secure.” The comparison is between postponing the run and the relevant alternative, which is understood from the context; it does not specify a numerical amount of safety. The useful chain is sicher → sicherer → am sichersten (“safe” → “safer” → “safest”). Putting the parts together, Den Lauf zu verschieben is the topic, bis sich die Luft verbessert gives the time limit (“until the air improves”), and scheint sicherer zu sein says that this choice seems safer. The complete meaning is: “Postponing the run until the air improves seems safer.”

10. So wird Sport nicht zu einem weiteren Gesundheitsproblem.

    That keeps exercise from turning into another health problem.

    So

    that way

    wird

    becomes; turns

    Sport

    exercise; sport

    nicht zu

    not into

    weiteren

    another; additional

    Gesundheitsproblem

    health problem

    More detail

    So means “in this way” or “that way.” Here it points back to the preceding idea without naming a new actor or changing the participants. A reusable pattern is So + clause: “That way, …” wird is the third-person singular present form of werden. In this sentence, werden + zu + noun expresses a change into a state or category: “becomes/turns into.” Example: Das wird zu einem Problem. — “That turns into a problem.” Sport is a masculine noun meaning “sport” or, in this context, “exercise.” Its form is the same here for the singular nominative and accusative; the sentence uses it as the subject of wird. Example: Sport ist gesund. — “Exercise is healthy.” nicht zu supplies the negation of the change: “not into.” nicht negates the wird ... zu relationship, so the meaning is that the exercise does not turn into the stated problem. weiteren comes from weiter, which can mean “further” or “additional.” In ein weiterer / einem weiteren, it commonly means “another” or “an additional one.” The ending -en is the adjective’s form after the dative singular article einem in this noun phrase. This form is not the noun’s ending and does not itself identify a quantity; another is the intended meaning here. Example: Wir brauchen einen weiteren Tag. — “We need another day.” Gesundheitsproblem is a compound noun: Gesundheit (“health”) + Problem (“problem”), meaning “health problem.” Its base form is das Gesundheitsproblem; the plural is die Gesundheitsprobleme. In einem weiteren Gesundheitsproblem, the neuter noun phrase is in the dative singular, required by the zu construction. The noun itself has no visible ending in this form. Together, So wird Sport nicht zu einem weiteren Gesundheitsproblem means “That keeps exercise from turning into another health problem.” The structure is So + wird + subject Sport + negated change nicht zu + einem weiteren Gesundheitsproblem.
