How to say "mostly" in Japanese
Choosing the right word
- adverbFor 'mostly' meaning 'on the whole, more or less' — a rough, approximate judgment. Suits statements like 'I mostly understand' or 'the work is mostly done,' where precision is not the point.
- adverbFor 'mostly' meaning 'nearly all, almost entirely' — the largest part with only a small remainder. Fits 'most of the students attended' or 'the bottle is mostly empty'; it stresses near-completeness.
- 主におもにadverbFor 'mostly' meaning 'mainly, primarily' — singling out the principal element among several. Typical when describing what something chiefly consists of or focuses on, as in a diet or activity that is mostly one thing.
- na-adjective, adverb, nounFor 'mostly' describing what usually or ordinarily happens — habitual frequency rather than proportion. Suits 'I'm mostly home in the evenings' or 'we mostly walk,' where the point is a usual pattern.
- 九分くぶnoun, adverbFrames 'mostly' as a literal proportion — nine parts out of ten, ninety percent. It is really a way of stating degree numerically, and is seldom the everyday adverb you want for plain 'mostly.'
Choose 「だいたい」 for rough 'on the whole' judgments, 「ほとんど」 for 'nearly all', 「主に」 for 'mainly', 「たいてい」 for habitual 'usually', and 九分 only when you want the literal nine-tenths, ninety-percent sense.
