   More detail

   aire means “air” here. It is a masculine singular noun: el aire. The same noun appears again later in the sentence as part of del aire; del combines de + el and means “of the.” se siente means “feels” in this sentence. It is the third-person singular present form of sentirse (“to feel”), used here for a subject such as el aire: El aire se siente pesado = “The air feels heavy.” The se belongs to this pronominal verb; it is not a separate translation of “it.” pesado means “heavy.” It is the masculine singular form of pesado, agreeing with masculine singular aire. Compare pesada with a feminine singular noun, as in La mochila se siente pesada — “The backpack feels heavy.” hoy means “today” and places the statement in the present day. It does not change form for the subject. calidad means “quality.” It is a feminine singular noun: la calidad. In la calidad del aire, it means “the quality of the air”; del aire identifies what kind of quality is being discussed. puede ser means “may be” here. It combines third-person singular present puede, from poder (“can; may”), with the infinitive ser (“to be”). This combination expresses possibility, not certainty: La calidad puede ser mala = “The quality may be poor.” mala means “bad” or, for air quality, naturally “poor.” It is the feminine singular form of malo, agreeing with feminine singular calidad. Compare masculine singular malo, as in El resultado puede ser malo — “The result may be poor.” Together, El aire se siente pesado hoy says that the air feels heavy today. y links that statement to la calidad del aire puede ser mala, which says that the air quality may be poor. The complete meaning is: “The air feels heavy today, and air quality may be poor.”

2. Entonces, quizá no sea buena idea hacer ejercicio al aire libre.

   Outdoor exercise might not be a good idea, then.

   Entonces

   then

   quizá

   perhaps

   no sea

   not be

   buena

   good

   idea

   idea

   hacer

   to do; to make

   ejercicio

   al aire libre

   outdoors

   More detail

   Entonces means “then” here and links this conclusion to the situation already described. It can also refer to a time in other sentences, but here it marks a consequence or conclusion. quizá means “perhaps” or “maybe.” It presents the statement as uncertain. A common alternative is quizás, with the same basic meaning. no sea is the negative form of ser (“to be”) in the present subjunctive: sea is the third-person singular form, and no negates it. After quizá, Spanish can use the subjunctive when the speaker presents the possibility as uncertain: Quizá sea tarde means “It might be late.” Here, no sea means “might not be,” not a definite “is not.” buena is the feminine singular form of the adjective bueno (“good”). It agrees with the feminine singular noun idea: una buena idea. The masculine singular form is bueno, as in un buen plan; before some masculine singular nouns, bueno becomes buen. idea is a feminine noun meaning “idea.” In the pattern ser una buena idea, Spanish evaluates a proposed action or situation: Es una buena idea descansar means “It is a good idea to rest.” hacer is the infinitive of “to do” or “to make.” In hacer ejercicio, it is part of the usual expression for “to exercise.” The infinitive can name an activity: Hacer ejercicio ayuda means “Exercising helps.” ejercicio means “exercise.” In this sentence it refers to physical exercise as an activity. Hacer ejercicio is the reusable combination “to exercise”; it does not require an article in this general activity meaning. al aire libre means “outdoors” or “in the open air.” al is the contraction of a and el, but the whole expression functions as a fixed location or setting phrase. For example, Comemos al aire libre means “We eat outdoors.” Together, hacer ejercicio al aire libre is the activity “exercising outdoors.” The pattern ser una buena idea + infinitive evaluates an action, while quizá no sea makes that evaluation uncertain and negative. Thus the complete utterance means: “Outdoor exercise might not be a good idea, then.”

3. Pensaba correr en el parque.

   I was planning to run in the park.

   Pensaba

   I was planning

   correr

   to run

   parque

   park

   More detail

   Pensaba is the first-person singular imperfect form of pensar (“to think”). Here, pensaba + infinitive expresses a past intention or plan: “I was planning to …” The imperfect presents that thought as ongoing or as background, without saying whether the plan was carried out. Example: Pensaba estudiar. — “I was planning to study.” correr is the infinitive of “to run.” After pensar in this meaning, the infinitive names the intended action: pensaba correr (“I was planning to run”). The infinitive does not mark the subject separately here; the subject is understood from pensaba as “I.” Example: Pensamos viajar mañana. — “We are planning to travel tomorrow.” parque is a masculine singular noun meaning “park.” In the utterance it appears with the definite article el, forming el parque (“the park”). The preposition en indicates location, so en el parque means “in the park.” Example: Corro en el parque. — “I run in the park.” Together, Pensaba correr gives the past intention “I was planning to run,” and en el parque specifies the location of the planned activity. The complete utterance therefore means: “I was planning to run in the park.”

4. Si la contaminación te molesta, elige hacer ejercicio en interiores.

   If pollution bothers you, choose an indoor workout instead.

   Si

   if

   contaminación

   pollution

   molesta

   bothers

   elige

   choose

   hacer

   do

   ejercicio

   exercise

   interiores

   indoors

   More detail

   Si introduces a condition: “if …”. The reusable pattern is si + a clause, followed by the result or advice. Example: Si llueve, me quedo en casa. — “If it rains, I stay at home.” contaminación is a feminine singular noun meaning pollution. Its base form is the same form used here; the article or adjective around it would show its feminine singular agreement, as in la contaminación ambiental — “environmental pollution.” molesta comes from molestar, “to bother” or “to annoy.” Here it is the present-tense third-person singular form because la contaminación is the thing causing the annoyance. Spanish commonly expresses this meaning with the thing that causes the feeling as the grammatical subject and the affected person as an object: La música me molesta. — “The music bothers me.” In the fixed sentence, te identifies the affected person as “you.” elige comes from elegir, “to choose,” and is an affirmative command for singular tú: “choose.” It is not the form for usted or for plural listeners. Example: Elige una opción. — “Choose an option.” hacer is the infinitive “to do” or “to make.” After elige, it names the action being chosen: elige hacer ... means “choose to do ...”. Example: Elige descansar. — “Choose to rest.” ejercicio is a masculine singular noun meaning exercise or physical exercise. The expression hacer ejercicio is a common combination meaning “to exercise” or literally “to do exercise”; ejercicio is not being used as a specific countable workout here. Example: Hago ejercicio por la mañana. — “I exercise in the morning.” interiores is the plural form of interior, used here in en interiores to mean indoors or in indoor spaces. The plural form fits the general reference to interior spaces rather than one specifically named room. Example: El entrenamiento se realiza en interiores. — “The training takes place indoors.” Together, Si la contaminación te molesta means “If pollution bothers you.” The condition has la contaminación as the source of the annoyance, while te marks the person affected. elige hacer ejercicio means “choose to exercise,” and en interiores specifies that the exercise takes place indoors. Thus the complete utterance means: “If pollution bothers you, choose to exercise indoors.” In the supplied context, this presents indoor exercise as the alternative to running in the park; the target sentence itself does not need a separate word for “instead.”

5. Podría usar el gimnasio, aunque allí me relajo menos que en el parque.

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

   Podría

   could

   usar

   use

   gimnasio

   gym

   aunque

   although

   allí

   there

   me relajo

   I relax

   menos que

   less than

   parque

   park

   More detail

   Podría is the conditional form of poder (“to be able to/can”). Here, together with the following infinitive, it expresses a possible option: “I could use…”. The conditional can soften a proposal or present an option rather than a firm plan. Example: Podría esperar. — “I could wait.” usar is the infinitive “to use.” After a form of poder, Spanish uses the infinitive: podría usar = “I could use.” Example: Puedo usar esta mesa. — “I can use this table.” gimnasio means “gym.” The article el before it marks this noun as masculine singular: el gimnasio. Example: El gimnasio está cerca. — “The gym is nearby.” aunque introduces a contrast and means “although/even though.” It does not cancel the first idea; both ideas remain part of the sentence. Example: Voy, aunque estoy cansado. — “I’m going, although I’m tired.” allí means “there,” referring to a place understood from the context. In this sentence, it points to the gym just mentioned. It is a location adverb, so it does not change for gender or number. me relajo means “I relax.” The verb is relajarse, and me is the first-person singular reflexive pronoun used with the subject “I.” The present-tense form relajo agrees with that subject. Example: Me relajo en casa. — “I relax at home.” menos que creates a comparison meaning “less than.” Here it compares how much the speaker relaxes in the gym with how much the speaker relaxes in the park. Menos is the comparative word; the comparison is completed by que. Example: Duermo menos que antes. — “I sleep less than before.” parque means “park.” The full source phrase has el parque, with the masculine singular article el: “the park.” Example: Camino en el parque. — “I walk in the park.” Together, Podría usar el gimnasio says “I could use the gym.” Aunque allí me relajo menos que en el parque adds the contrast: “although I relax less there than in the park.” The complete meaning is: “I could use the gym, although it feels less relaxing than the park.”

6. Entrenar en interiores es más saludable que respirar aire de mala calidad.

   Training indoors is healthier than breathing poor air.

   Entrenar

   to train

   en interiores

   indoors

   es

   is

   más saludable

   healthier

   respirar

   to breathe

   aire

   air

   mala

   poor

   calidad

   quality

   More detail

   Entrenar is the infinitive “to train.” Here it functions as the subject of the sentence, so the activity itself is being evaluated. Spanish infinitives can work as noun-like subjects: Caminar ayuda means “Walking helps.” en interiores means “indoors,” literally locating the activity inside buildings or enclosed spaces. It is a reusable location pattern: trabajar en interiores means “to work indoors.” es is the present-tense form of ser for a singular subject. In this sentence, the singular subject is the activity expressed by Entrenar, not a person. The form ser is the infinitive; es is its present indicative form here. más saludable is the comparative “healthier.” The adjective saludable means “healthy,” and más saludable compares it with something else. The pattern más + adjective + que means “more adjective than”: Este aire es más limpio que aquel means “This air is cleaner than that one.” respirar is the infinitive “to breathe.” It introduces the other activity used in the comparison: the sentence compares training indoors with breathing poor-quality air. As with Entrenar, an infinitive can name an activity. aire means “air.” It is a masculine singular noun, as shown by the following adjective form mala not agreeing with it directly here; instead, mala agrees with calidad in the noun phrase aire de mala calidad. mala means “poor” or “bad” in this context. It is the feminine singular form of malo, agreeing with calidad, which is feminine singular. The masculine singular form is malo; for example, un mal resultado means “a poor result,” where mal appears before a masculine singular noun. calidad means “quality.” In aire de mala calidad, the preposition de links aire to the quality it has: “air of poor quality,” naturally “poor-quality air.” Calidad is feminine singular, which is why the adjective is mala rather than malo. Together, Entrenar en interiores is the activity being evaluated, and es más saludable que introduces a comparison. The comparison is with respirar aire de mala calidad, “breathing poor-quality air.” Thus the complete meaning is: “Training indoors is healthier than breathing poor air.”

7. ¿Debería usar una mascarilla si necesito caminar afuera?

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

   Debería

   should

   usar

   to wear; to use

   mascarilla

   mask

   si

   if

   necesito

   I need

   caminar

   to walk

   afuera

   outside

   More detail

   Debería is a form of deber meaning “should” here. With the fixed translation, it expresses the speaker’s question about what they ought to do: “Should I …?” The form debería can also agree with other singular subjects in other contexts, so the ending alone does not identify the subject; the intended first-person subject is supplied by the question’s meaning. usar is the infinitive of usar, “to use.” With clothing or protective equipment, Spanish commonly uses usar where English may say “wear”: usar una mascarilla means “wear/use a mask.” The infinitive follows debería: debería usar = “should wear.” mascarilla is a feminine noun meaning “mask,” especially a protective face mask in this context. The feminine article is una; it introduces the noun but does not by itself assert a numeric count. Example: La mascarilla ayuda = “The mask helps.” si introduces a condition and means “if.” The pattern si + clause presents the situation under which the main action is considered. It is different from accented sí, which means “yes.” necesito is the first-person singular present form of necesitar, “to need.” Its subject is “I,” and it agrees with that subject: necesito caminar = “I need to walk.” Example: Necesito descansar = “I need to rest.” caminar is the infinitive of caminar, “to walk.” After necesito, the infinitive names the action that is needed: necesito caminar = “I need to walk.” afuera is an adverb meaning “outside” or “outdoors.” It describes where the walking takes place and does not change for gender or number. Example: Quiero esperar afuera = “I want to wait outside.” Together, debería usar una mascarilla asks whether wearing a mask is advisable, while si necesito caminar afuera supplies the condition “if I need to walk outside.” The complete utterance therefore means: “Should I wear a mask if I need to walk outside?”

8. Una mascarilla puede ayudar, y las recomendaciones sanitarias locales pueden sugerir precauciones adicionales.

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

   mascarilla

   mask

   puede

   can / may

   ayudar

   help

   recomendaciones

   recommendations or advice

   sanitarias

   health-related

   locales

   local

   sugerir

   suggest

   precauciones

   precautions

   adicionales

   additional or extra

   More detail

   mascarilla means “mask” here. It is a feminine noun: una mascarilla uses the feminine singular indefinite article. Its plural is mascarillas. Example: La mascarilla está limpia. — “The mask is clean.” puede is the third-person singular present form of poder, “can” or “may.” Here it agrees with singular mascarilla and expresses possibility or potential. poder is followed by an infinitive: puede ayudar means “can help.” Example: El descanso puede ayudar. — “Rest can help.” ayudar is the infinitive “to help.” After puede, Spanish uses the infinitive rather than a separately conjugated verb. The same verb can be used with other subjects: Puedo ayudar. — “I can help.” recomendaciones is the plural of the feminine noun recomendación, meaning “recommendation” or, in this context, “advice.” The plural form helps identify it as the subject of the second clause. Example: Las recomendaciones son útiles. — “The recommendations are useful.” sanitarias is the feminine plural form of the adjective sanitario, meaning “health-related” or “health.” It agrees with feminine plural recomendaciones. The masculine singular, for example, is sanitario, but adjective form must match the noun it describes. locales is the plural form of local, meaning “local.” In this sentence it also agrees with plural recomendaciones. This adjective has the same form for masculine and feminine plural nouns: for example, servicios locales and recomendaciones locales. pueden is the third-person plural present form of poder. It agrees with the plural subject las recomendaciones sanitarias locales, so the sentence uses pueden, not singular puede. Together with the following infinitive, pueden sugerir means “may/can suggest.” sugerir is the infinitive “to suggest.” It follows pueden, just as ayudar follows the first puede. Example: Los datos pueden sugerir un cambio. — “The data may suggest a change.” precauciones is the plural of the feminine noun precaución, meaning “precaution.” The adjective adicionales agrees with it in feminine plural. Example: Tomamos precauciones adicionales. — “We take extra precautions.” adicionales means “additional” or “extra.” It is the plural form of adicional; here it modifies plural precauciones. The adjective has the same form for masculine and feminine plural nouns, as in medidas adicionales (“additional measures”). The utterance has two coordinated clauses joined by y (“and”). First, Una mascarilla puede ayudar says that a mask can help. Second, las recomendaciones sanitarias locales pueden sugerir precauciones adicionales says that local health recommendations may suggest extra precautions. The two modal forms agree with their respective subjects: singular mascarilla takes puede, while plural recomendaciones takes pueden.

9. Parece más seguro posponer la carrera hasta que mejore el aire.

   Postponing the run until the air improves seems safer.

   Parece

   seems

   más seguro

   safer

   posponer

   to postpone

   la carrera

   the run

   hasta que

   until

   mejore

   improves

   el aire

   the air

   More detail

   Parece is the present-tense third-person singular form of parecer, “to seem” or “to appear.” In this sentence, the thing that seems a certain way is the infinitive phrase that follows: “postponing the run...” Example: Parece difícil. — “It seems difficult.” más seguro means “safer.” Seguro is the base adjective “safe,” and más seguro forms the comparative with más + adjective. The adjective is masculine singular here because it describes the postponing expressed by the infinitive phrase, which is treated grammatically as singular and masculine in this construction. Example: Este camino es más seguro. — “This route is safer.” Posponer is the infinitive “to postpone.” It names the action being evaluated, rather than marking a particular person or time. After parece, an infinitive phrase can function as the subject: Parece mejor esperar. — “Waiting seems better.” La carrera means “the run” here, as established by the fixed translation. Carrera is a feminine singular noun, so it takes the feminine singular article la. Depending on context, carrera can also refer to a race or a career, but those are not the intended meanings here. Example: La carrera empieza temprano. — “The run starts early.” Hasta que introduces the point up to which something is postponed: “until.” When that condition is viewed as pending or anticipated, Spanish uses the subjunctive in the following clause. Example: Esperaremos hasta que llegue. — “We will wait until he or she arrives.” Mejore is the present subjunctive, third-person singular form of mejorar, “to improve.” Its subject here is el aire, so the meaning is “the air improves.” The subjunctive is selected because the improvement is a condition still awaited, not a stated completed fact. Example: Abriremos la ventana cuando mejore el tiempo. — “We will open the window when the weather improves.” El aire means “the air.” Aire is a masculine singular noun in this use, which is why it takes el. In the sentence, it is the subject of mejore. Together, posponer la carrera gives “postpone the run,” and hasta que mejore el aire specifies “until the air improves.” The full structure is Parece + más seguro + infinitive phrase + hasta que + subjunctive clause: “Postponing the run until the air improves seems safer.”

10. Eso evita que el ejercicio se convierta en otro problema de salud.

    That keeps exercise from turning into another health problem.

    Eso

    That

    evita

    prevents

    ejercicio

    exercise

    se convierta

    turns into

    otro

    another

    problema

    problem

    salud

    health

    More detail

    Eso is a demonstrative pronoun meaning “that.” It refers to an already established situation or action; here, the fixed translation presents it as the thing that prevents the result described next. Its exact referent is not a noun inside this sentence. evita is the present-tense third-person singular form of evitar, “to prevent” or “to avoid.” The form agrees with the singular subject eso. A useful pattern is evitar que + a subordinate clause: “to prevent something from happening.” Example: La pausa evita que el problema empeore. — “The break prevents the problem from getting worse.” el ejercicio means “exercise.” Ejercicio is a masculine singular noun, so it appears with the masculine singular article el here. The noun can refer to physical activity, as in this sentence, or to a practice task in another context; the fixed translation supports the physical-activity meaning here. se convierta comes from the pronominal verb convertirse en, “to turn into” or “to become.” Convierta is the present subjunctive third-person singular form of convertir, used here with se; the subjunctive is selected in the subordinate clause after evita que. The construction is convertirse en + noun: El cansancio se convierte en un problema. — “Tiredness turns into a problem.” otro means “another” or “an additional.” It is a masculine singular form because it agrees with problema, which is masculine singular. Compare otra situación for a feminine singular noun and otros problemas for masculine plural nouns. problema means “problem.” Although it ends in -a, it is conventionally masculine in Spanish, as shown by el and otro: el problema, otro problema. de salud means “health” in the relationship “health-related.” Salud is a feminine noun, but there is no article inside this noun phrase; de salud functions as a compact modifier of problema. For example, un riesgo de salud means “a health risk.” Together, Eso evita que introduces the prevented result, and el ejercicio se convierta en otro problema de salud says that exercise would turn into an additional health problem. The whole utterance therefore means: “That keeps exercise from turning into another health problem.”
