How to Say “It Was” in Japanese

だった
datta
The English phrase "it was" can be expressed in Japanese as だった (datta).
だった is used to describe a state or identity in the past.

Which one should you use?

だった is used for the past tense of the copula (the verb 'to be'), whereas でした is the polite version of the same expression. If you are referring specifically to the existence or presence of something in the past, you would use ありました instead of だった.

Is there a formal and an informal way to say it?

だった is an informal way to say "it was", suitable for casual speech with friends or for writing in a diary. In polite speech, such as when talking to strangers or superiors, you should use でした. When referring to the existence of something in the past, the formal version is ありました and the colloquial version is あったんだ.

How does it change in a sentence?

だった is the plain, informal past tense of the copula used with nouns and na-adjectives.

How do you pronounce it?

datta

Did you know?

  • While だった translates to 'it was', using it in a sentence with a person's name can sometimes sound like you are talking about a dead person or a character in a book, depending on the context.
  • The word だった is actually a contraction of であった, an older, more formal way of expressing the past tense. While it sounds casual now, its roots are deeply embedded in classical Japanese grammar.
  • If you want to say 'it was' to emphasize a discovery or a sudden realization, you might add the particle んだ to make it だったんだ. This adds a nuance of explanation or emotional weight that 'it was' lacks in English.
