いつか
itsuka[it͡sɨka̠]
The English phrase "someday" is translated into Japanese as いつか (itsuka).
いつか is used to refer to an unspecified point in the future, equivalent to saying "sometime" or "someday".
Meaning: sometime, at some time in the future (adv)
What does it mean word for word?
The word is a combination of itsu (when) and the indefinite particle ka (a question or uncertainty marker), literally meaning "some when".
Which one should you use?
While いつか refers to an indefinite future time, it is distinct from a phrasing that might be confused with itsu (when) plus a particle. In standard usage, いつか specifically refers to an unspecified point in the future.
How do you pronounce it?
itsuka
Did you know?
- Using いつか can sometimes sound like a polite way of saying 'never' if the speaker is avoiding giving a concrete date for a promise.
- In Japanese, the same pronunciation いつか can also be written with different kanji to mean 'once' or 'some time ago', depending on the context and writing system used.
- In certain contexts, いつか can be used to express a vague threat, implying that a reckoning will come at an unknown time.
