Interjections are words that express emotions. They are followed by an exclamation point or a comma.
Examples:
Wow! That bird is big. —Well, I don’t think that is a bird.
In the sentences above, “wow” and “well” are interjections.
間投詞は、感情を表す言葉です。その後に、感嘆符やコンマが来ます。
例:
Wow! That bird is big. (わあ。あの鳥は大きいですね。)
Well, I don’t think that is a bird.(うーん、あれは鳥じゃないと思いますよ。)
上の文では、wowとwellが間投詞です。
