grammatical
1. depending on — used after a noun to say that an outcome varies according to that factor
A fixed pattern [noun] + 次第(しだい)で, meaning 'depending on [noun]' or 'according to [noun]'. It introduces a factor that will determine or influence the result of something. The related form 次第(しだい)だ ends a sentence ('it depends on X'), and 次第(しだい)では adds a stronger conditional nuance ('depending on the circumstances').
天気(てんき)次第(しだい)()めます
I'll decide depending on the weather.
The result depends on your effort.
Depending on how you use it, this tool can be very useful.
Depending on the price, I'm willing to buy it.

Fixed pattern: [noun] + 次第(しだい)で / 次第(しだい)です / 次第(しだい). The element 次第(しだい) is a noun meaning 'order' or 'circumstances', and attaching で turns the whole phrase into 'depending on X'.

Usage

  • [noun] + 次第(しだい)で: depending on [noun] (used mid-sentence). The outcome varies with the noun.
  • [noun] + 次第(しだい)だ/です: it depends on [noun] (sentence-ending). Common as a complete statement: '結果(けっか)(きみ)次第(しだい)だ' (the result depends on you).
  • [noun] + 次第(しだい): depending on [noun] (with a stronger conditional nuance, often introducing a contingency).
  • Attaches only to NOUNS, not directly to verbs or adjectives. To follow a verb, use a nominalized form such as 使(つか)(かた) or similar nouns.
