～なあ (exclamatory particle)

• 読み: なあ
• ローマ字: naa
• 形: Sentence (plain form) + なあ

意味

A sentence-final particle used in informal male speech to express strong emotion such as admiration, longing, or deep feeling. It adds an exclamatory or reflective nuance to the statement.

なあ is primarily associated with male speech and conveys heartfelt emotion — whether admiration, nostalgia, frustration, or wishful thinking. It differs from ね in that ね seeks agreement from the listener, while なあ is more self-directed and emotionally expressive. When used with たい (e.g., 行きたいなあ), it expresses a strong personal wish. Women may also use it in very casual settings, but it retains a masculine tone. The vowel is often elongated in speech for extra emphasis. It should not be confused with the explanatory な (short for なの) or the prohibitive な.

例文

1. 今日の夕焼けはきれいだなあ。
