How to say "great" in Japanese

Choosing the right word
  • 大きいおおきいJLPT N5approx.Common
    i-adjectiveIts 'great' means large in size or degree, as in a great difference or a great big building; it is not used to praise a person or call something wonderful.
    きみは何なんと大おおきい家いえを持もっているんだろう。↗
    What a big house you have!
  • 大おおCommon
    prefixThe reading おお of 大 typically appears as the first element of larger words, adding a sense of large, great or major; by itself it is not how you say something is great.
    大口おおぐち叩たたきは何なんもできない。↗
    Great talkers are little doers.
  • 大だいJLPT N3approx.Common
    prefix, na-adjective, nounThe on-reading だい of 大, found chiefly inside compound words rather than used by itself; there it contributes large, big, great or huge, but as a standalone way to say 'great' it is marginal.
    この決定けっていはあなたの提案ていあんに負おうところ大だいであった。↗
    Your suggestion weighed heavily in this decision.
  • 大きなおおきなJLPT N5approx.Common
    pre-noun adjectivalSame meaning as 大きい, but it only modifies nouns and cannot end a sentence; it works before a noun for both physical size and abstract 'great', as in a great problem.
    アメリカ人あめりかじんの中なかには大おおきな借金しゃっきんを抱かかえている人ひとがいる。↗
    Some Americans have grave debts.
  • えらいJLPT N2approx.Common
    i-adjectiveThis is 'great' in the sense of admirable or praiseworthy, used of a person or their deeds, as when telling a child they did great; it has nothing to do with physical size.
    私はあの人ひとが将来しょうらい偉えらくなると見取みとった。↗
    I discerned the potential of great things in him.

Use 「大きい」 or 「大きな」 for 'great' meaning large in size or degree, 大(おお) and 大(だい) as elements of larger words, and 「えらい」 for 'great' meaning admirable or praiseworthy.
