～のみ

• Reading: のみ
• Romaji: nomi
• Formation: Noun + のみ / Verb (plain form) + のみ / Particle + のみ

Meaning

A formal particle meaning 'only' or 'solely.' It expresses a limit imposed upon an action, event, or state, functioning as a more literary equivalent of だけ.

のみ is the formal counterpart of だけ and is frequently found in written documents, official announcements, regulations, academic texts, and news articles. While だけ is used freely in conversation, のみ sounds stiff and overly formal in casual speech. A common compound form is のみならず (not only), which is the formal equivalent of だけでなく. Unlike しか (which requires a negative predicate), のみ can appear with both affirmative and negative predicates. Learners sometimes use のみ in casual conversation, which sounds unnatural, or confuse のみ with ばかり, which implies excess rather than limitation.

3. 参加を希望する方のみお申し込みください。 Only those who wish to participate, please apply.
