How to say "major" in Japanese
Choosing the right word
- na-adjective, nounA katakana loanword covering 'major' in the major-versus-minor sense: prominent, famous, big-league. It suits talk of major companies, major sports, or a major label, not the military rank of major.
- 少佐しょうさnounStrictly the military rank of major, with lieutenant commander as the navy equivalent. If 'major' is an officer's rank, this is the word; for any other sense of 'major' it is irrelevant.
- 大おおprefixThe おお reading of 大 is essentially 'big; great': it conveys size or greatness, and on its own it is seldom the word you want for 'major' — 重要 or メジャー serve that sense better.
- 大だいprefix, na-adjective, nounThe だい reading of 大 means 'large; big; great; huge'. It matches 'major' only where 'major' is really about size, so for 'major' as 'important' this is not the word you want.
- 重要じゅうようna-adjectiveYour word for 'major' meaning important or significant: a major problem, decision, or role. It is about importance rather than size, fame, or rank, so it fits serious matters and their consequences.
For the military rank choose 少佐; for 'major' meaning important or significant choose 重要; for major-versus-minor prominence choose 「メジャー」; the two readings of 大 mean 'big; great' and are seldom the word for 'major'.
