Borrowing a Cable for a Phone Battery Problem | Learn Japanese in English

Sentence explanations

1. スマホのバッテリーがほとんど切れています。

   My phone battery is almost dead.

   スマホ

   smartphone

   バッテリー

   battery

   ほとんど

   almost

   切れています

   is depleted

   More detail

   スマホ means “smartphone.” It is a common shortened form of スマートフォン. The form itself does not mark number, so it can refer to one smartphone or smartphones depending on context; here it is the phone whose battery is being discussed. バッテリー means “battery.” In スマホのバッテリー, の links the two nouns: “the smartphone’s battery” or “the battery of the smartphone.” ほとんど means “almost” or “nearly.” Here it indicates that the battery is very close to being depleted, not that it is completely depleted. A useful pattern is ほとんど + state or amount, as in ほとんど終わりました (“It is almost finished”). 切れています comes from 切れる, “to run out, be depleted, or stop functioning,” not from the transitive verb 切る, “to cut.” 切れています combines the て-form with います and presents the resulting state as continuing: the battery is currently depleted or nearly depleted. The polite ending ます makes the statement suitable for ordinary polite conversation. In this sentence, the form is used for a battery running out; the same verb can describe other things running out or ceasing to work, depending on its object and context. The particle が marks スマホのバッテリー as the subject of the state. Together, スマホのバッテリーが (“the smartphone’s battery”) + ほとんど (“almost”) + 切れています (“is depleted”) produces: “My phone battery is almost dead.” Japanese does not explicitly mark the possessor as “my” here; that reading comes from the fixed translation and context.

2. 充電器かモバイルバッテリーを持っていますか。

   Do you have a charger or power bank with you?

   充電器

   charger

   か

   or

   モバイルバッテリー

   power bank

   持っていますか

   do you have ...?

   More detail

   充電器 means “charger” here. It is a noun; the same form can be reused when naming a charger as the object of another verb. For example: 充電器を使います。 — “I use a charger.” か placed between two noun phrases links alternatives, so here it means “or.” This is different from sentence-final か, which commonly marks a question. The pattern AかB means “A or B.” モバイルバッテリー is a noun meaning “power bank” or “portable battery.” It is a loanword expression, and it names the second alternative in this question. For example: モバイルバッテリーを買いました。 — “I bought a power bank.” 持っていますか asks whether someone has or is carrying something. The base verb is 持つ (“to have, hold, or carry”); 持っている expresses the resulting or continuing state of having/carrying it, and 持っています is its polite form. Final か makes the clause a question, but in this sentence the earlier か after 充電器 is the “or” linker. For example: 傘を持っていますか。 — “Do you have an umbrella?” Together, 充電器かモバイルバッテリー gives the alternatives “a charger or a power bank.” The object marker を marks that alternative phrase as what is had or carried, and 持っていますか asks the listener about that state. Thus the whole utterance means: “Do you have a charger or power bank with you?”

3. 両方とも家に置いてきました。

   I left both at home.

   両方とも

   both

   家

   home; house

   置いてきました

   left (something) behind

   More detail

   両方とも means “both” here. 両方 is used for two sides or two items, and とも adds the sense that both are included. In the supplied context, it refers to both the charger and the power bank. 家 means “home” or “house.” Here it is followed by に, which marks the place where the items were left: 家に = “at home.” The noun itself does not change form for this use. 置いてきました is the polite past form of 置いてくる. The base verb 置く means “to put” or “to leave” something in a place. Its て form is 置いて, followed by くる (“come”); together, 置いてくる describes leaving something at a place and coming away from it. きました is the polite past form of くる, so 置いてきました means “left behind” in this context. Compare 置きました, “put/left [something]” without the added idea of coming away. The chunks combine as 両方とも + 家に + 置いてきました: “both” + “at home” + “left behind.” Japanese leaves the subject unspoken here; with the fixed translation, the sentence means “I left both at home.”

4. 急ぎの電話をかける必要があります。

   I need to make an urgent call.

   急ぎの

   urgent

   電話

   phone call

   かける

   make (a call)

   必要があります

   need to

   More detail

   急ぎの means “urgent” here. 急ぎ is a noun meaning urgency or something needing prompt attention, and の links it to the following noun: 急ぎの電話 = “an urgent call.” This is a noun-modifying pattern: [noun]の[noun]. 電話 means “telephone” or “phone call.” In this sentence, the intended meaning is a call as an activity. The common pattern 電話をかける means “to make a phone call”; を marks 電話 as the object of かける. かける is the dictionary form of the verb meaning “to make” in the established expression 電話をかける. The same verb has other meanings in other contexts, so its meaning here comes from its combination with 電話. For example, 友達に電話をかけます。 means “I will call a friend.” 必要があります expresses necessity: literally, “there is a need.” 必要 is a noun meaning “necessity” or “need,” and あります is the polite nonpast form of ある, “to exist.” The pattern Vる必要があります means “need to V” or “it is necessary to V.” Here, かける is the plain-form verb placed before 必要, producing かける必要があります = “need to make [a call].” The polite marking is carried by あります, not by かける. Together, 急ぎの電話 identifies the call as urgent, while かける必要があります says that making it is necessary. The full utterance therefore means “I need to make an urgent call.”

5. 窓のそばにコンセントがあります。

   There is an outlet beside the window.

   窓

   window

   のそばに

   beside; near

   コンセント

   outlet

   あります

   there is; exists

   More detail

   窓 means “window” here. It is a noun, so it can be followed by particles to show its relation to another word. Example: 窓を開けます。 — “I open the window.” のそばに places something near the noun before の: 窓のそばに means “beside the window” or “near the window.” The pattern [place]のそばに is reusable for locating something. Example: 机のそばにかばんがあります。 — “There is a bag beside the desk.” Here に marks the location where something exists. コンセント means “electrical outlet” in this sentence. It is a noun commonly used for the socket into which a plug is inserted. Example: コンセントを使います。 — “I use the outlet.” あります is the polite nonpast form of ある, used here to say that an inanimate thing exists at a location. The corresponding polite form for a living being is います; this is a distinction between the type of thing that exists, not a distinction between locations. Example: 部屋にいすがあります。 — “There is a chair in the room.” Together, 窓のそばに gives the location, コンセント identifies the thing, and あります states its existence politely. The complete utterance means: “There is an outlet beside the window.”

6. 数分間、あなたのケーブルを使ってもいいですか。

   Could I use your cable for a few minutes?

   数分間

   for a few minutes

   あなたの

   your

   ケーブル

   cable

   使ってもいいですか

   May I use it?

   More detail

   数分間 means “for a few minutes” here. 数 expresses an unspecified small number, and 分 counts minutes. The final 間 presents the period as a duration. For example: 十分間待ちます。 — “I will wait for ten minutes.” あなたの means “your”: あなた is “you,” and の links that possessor to the following noun. In this sentence, the fixed translation identifies the cable as belonging to the listener. The same pattern is reusable: 私の電話 — “my phone.” ケーブル is the noun “cable,” written in Japanese using a loanword spelling. It is the object of the requested use. For example: このケーブルを使います。 — “I use this cable.” 使ってもいいですか is a polite way to ask permission: “May I use it?” The base form is 使う (“to use”). Its て form, 使って, combines with もいい to express that doing the action is acceptable; ですか makes the question polite. The reusable pattern is V-てもいいですか — “May I V?” For example: ここに座ってもいいですか。 — “May I sit here?” Together, 数分間 sets the duration, あなたのケーブル identifies the object as the listener’s cable, and 使ってもいいですか asks politely for permission to use it. The whole utterance therefore means: “Could I use your cable for a few minutes?” This is a polite everyday request.

7. 電話をかけるのに十分な時間、使っていいですよ。

   You can use it long enough to make the call.

   電話

   telephone; call

   かける

   make (a call)

   のに

   in order to

   十分な

   enough; sufficient

   時間

   time

   使って

   use

   いいですよ

   it is okay; may

   More detail

   電話 means “telephone” or, in this context, “a call.” It is a noun. In 電話をかける, the particle を marks it as the object of the action. かける here means “to make a call.” Its base form is かける; with 電話を, this is the reusable pattern 電話をかける (“make a call”). The same verb has other uses in other combinations, so the noun phrase helps determine this meaning. のに here marks the purpose or situation of an action: 電話をかけるのに means “for making a call” or “to make a call.” In this use, の turns the preceding action into a noun-like expression and に marks its purpose. This is different from the concessive のに, meaning “although.” 十分な means “enough” or “sufficient.” 十分 is the base expression, and な connects it to the noun 時間: 十分な時間 means “enough time.” The な belongs to this descriptive expression, not to 時間. 時間 means “time.” In 十分な時間, it is the amount of time considered sufficient for the stated purpose. A reusable example is 読む時間が十分あります。 — “There is enough time to read.” 使って is the te-form of the verb 使う (“use”). The te-form connects the verb to what follows; in 使っていい, it forms a permission pattern. The subject is understood from the situation and the fixed translation as “you,” while the thing being used is understood as “it.” いいですよ means “it is okay” and, after a te-form, gives permission: 使っていいですよ means “you may use it” or “it is okay to use it.” ですよ adds an informing or reassuring tone; it does not itself identify the object. Together, 電話をかけるのに十分な時間 means “enough time to make a call.” The following 使っていいですよ grants permission to use it for that amount of time. Thus the whole utterance means: “You can use it long enough to make the call.”

8. スマホの電源が入ったら、すぐに返します。

   I will return it as soon as my phone turns on.

   スマホ

   smartphone

   電源

   power; power supply

   入ったら

   when it turns on

   すぐに

   immediately

   返します

   will return

   More detail

   スマホ means “smartphone.” It is a commonly used shortened noun; the fixed translation identifies it as the speaker’s phone in this context. 電源 means “power” or “power supply.” With a device, 電源が入る is the reusable expression “the power comes on” or “the device turns on.” Here, の links スマホ to 電源, giving “the smartphone’s power.” The particle が marks 電源 as what turns on. 入ったら comes from 入る (“to enter; to come on” in this device-related expression). Its form is 入った plus ら: 入ったら means “when/once it comes on” here. Although 入った has the shape of a past form, 〜たら can mark a condition or a future time, so it does not mean that the turning-on happened in the past. For example, 家に着いたら、電話します。 means “When I get home, I’ll call.” すぐに means “immediately” or “right away.” It says that the return will follow the phone turning on with little delay. 返します comes from 返す (“to return” or “give back”). The ending ます is the polite nonpast form; in this sentence, the fixed translation uses it for a future intention: “I will return it.” Japanese does not require the subject or object to be stated when they are understood. Here, the translation identifies the subject as “I” and the object as “it,” referring to the item being used in the surrounding exchange. 返す is transitive, so the returned item is understood even though it is omitted. Together, スマホの電源が入ったら sets the condition or time—“once the smartphone turns on”—and すぐに返します states that the speaker will return the understood item immediately, politely. The complete meaning is: “I will return it as soon as my phone turns on.”

9. バッテリーが十分になるまで、つないだままにしてください。

   Keep it plugged in until you have enough battery.

   バッテリー

   battery

   十分になる

   become sufficient

   つないだままにしてください

   please leave it connected

   More detail

   バッテリー means “battery.” It is a loanword noun. In this sentence, it is the thing whose sufficiency sets the endpoint of the action. 十分になる means “become sufficient” or “become enough.” 十分 expresses sufficiency, and なる means “become”; the form なる is the non-past form used here inside the time expression. The pattern X が 十分になる means “X becomes sufficient/enough.” For example, 水が十分になった means “There was enough water” or, more literally, “The water became sufficient.” まで means “until” when it follows the point or condition that marks an endpoint. Thus, バッテリーが十分になるまで means “until the battery becomes sufficient.” It describes how long the requested state should be maintained. つないだままにしてください is a request to leave something connected. The lexical verb is つなぐ, “connect”; its form here is つないだ, the past form used before まま, not a statement that the connecting happened at a particular past time. まま indicates that a state is left unchanged, so つないだまま means “remaining connected” or “still connected.” The omitted object is the thing that should remain connected; the fixed translation supports “it,” but does not identify that object more specifically. にする in the pattern 〜たままにする means to cause or allow a state to remain as it is. してください is the polite request form of する: して plus ください, “please do.” Together, つないだままにしてください politely asks the listener to leave it connected. This is different from simply つないでください, “please connect it,” which focuses on making the connection rather than maintaining the connected state. The full structure is バッテリーが十分になるまで、つないだままにしてください: “Please leave it connected until the battery becomes sufficient.” The comma separates the endpoint condition from the request, and the sentence politely specifies how long the connected state should continue.
