意味

A particle that indicates the boundary at which something ends, or the total amount of time, money, or quantity required for something. It sets a limit or scope for an action or state.

This で marks limits in two related ways. First, it sets a time or event boundary: 五時で閉まる (closes at five — five being the cutoff), 今日で終わりです (it ends as of today). Second, it marks quantities like cost, number, or duration: 三百円で買える (can buy for 300 yen), 三人で持ち上げた (lifted by three people), 一時間で着く (arrive in one hour). The common thread is that で defines the extent or scope within which something is accomplished or constrained. This differs from に for time, which marks a point when something occurs. Compare: 五時に来る (come at five) versus 五時で終わる (end at five — the limit).

例文

  1. このケーキは五百円で買えます。
  2. 授業は三時で終わります。

起源と歴史

This limiting で is an extension of the circumstantial で, defining the scope or boundary within which an event takes place. The notion of 'within these parameters' naturally developed into 'at this limit.'

関連フレーズ

～は～だ (copula) The most fundamental sentence pattern in Japanese. は marks the topic of the sentence, and だ (or its polite form です) functions as the copula, equivalent to English 'is,' 'am,' or 'are.' This structure is used to identify, describe, or classify the topic. が (subject marker) A particle that marks the grammatical subject of a sentence. が identifies who or what performs an action or exists in a state, and is especially used when presenting new or emphasized information. で (location of action) A particle that indicates the location where an action or event takes place. Unlike に, which marks the location of existence, で is used when something is actively happening at that location. で (means/instrument) A particle that indicates the tool, means, method, or material used to perform an action. It answers the question 'by what means?' or 'with what?' と (exhaustive listing) A particle used to connect nouns in an exhaustive list, meaning 'and.' When using と, the listed items are all there are — nothing is left out. と (reciprocal) A particle that marks the person or entity with whom an action is done together or reciprocally. It indicates a partner in mutual actions such as meeting, talking, playing, or fighting. に (destination) A particle that indicates the destination or goal toward which someone or something moves. It marks the arrival point of directional movement verbs such as 行く, 来る, and 帰る. に (existence location) A particle that indicates the location where someone or something exists. It is used exclusively with existence verbs such as いる (for animate beings) and ある (for inanimate objects).
