In the sentence:


If 初めて is an adverb, it should modify the phrase behind it, which is a rule of Japanese. So here it should modify「その本の本当の価値が分かるようになった」, but why there is a comma "、" between them?
After all, I don't see elsewhere an adverb and its modifying part are seperated by a comma. So I feel the original sentence is a little strange.

I came up with an explanation: maybe here we should see て初めて as a compound particle, which means "not until". But I think it's also Ok to see 初めて as a single adverb, and the sentence should be


just like the sentence:


in the second explanation of 初めて from デジタル大辞泉

You can put the comma in either of two places as below.



The two sentences give slightly different impressions. The first simply connects two statements. The speaker became a college student (first), and (then) realized the true value of the book for the first time. The second sentence places greater focus on when they made that realization as if to say it wasn’t until they became a college student that they realized the true value of the book. The whole of 大学生になって初めて could be seen as a temporal phrase.

The difference is very subtle.

  • Thanks! And do you think my explanation in the question body(to see て初めて as a whole compound particle in 大学生になって初めて) is reasonable?

  • @shepherd - It seems it’s one of the grammar points targeted for JLPT N3 as explained here and in other similar sites.

  • Thanks, I know! So て初めて is a whole part, and it should not to see 初めて in this structure as an adverb, right?

    @shepherd - スーパー大辞林 has this definition under はじめて, which it lists only as 副: ② (「…てはじめて」の形で)さまざまな経過を経てようやくその状態になるさま。やっと。「失って―偉大さに気づく」 I don’t think grammatical categorization is important here. At least native speakers don’t make such a distinction. Either way it works on the main verb 分かるようになった.

初めて is modifying the the sentence before the comma. Think of it as two separate phrases


Becoming a student for the first time

(A better translation of the phrase になって初めて by jisho is 'not until I became' or 'only when'.) This whole phrase modifies the expression after the comma.


I realized the true value of the book.

tl;dr: 初めて is part of the phrase before the comma

  • Yes, but if you say " 初めて is part of the phrase before the comma", here 初めて is not conceived as an adverb, right? If it's an adverb, it should modify the phrase behind it.
