Questions & Answers about kanojo wa hayaoki ga dekiru you ni natta.

What does the construction 〜ようになる mean here, beyond a simple ability?

It marks a change of state over time: “come to be (so that) …”. The inner clause before ように is a plain, non-past statement (here, 早起きができる). Together, [早起きができる] ように なった means she wasn’t able to before (or it wasn’t the case), but now she is.

• 彼女は早起きができる。 = She can wake up early. (ability as a fact now)
• 彼女は早起きができるようになった。 = She became able to wake up early. (there was a change)

Why is が after 早起き? Could I use を or drop the particle?

• With できる, the thing you can do takes が: N が できる. Since 早起き is a noun (a する-noun), you say 早起きができる.
• Using を with できる (e.g., 早起きをできる) is generally incorrect.
• In casual speech, speakers often drop the inner が: 早起きできるようになった. This is fine in informal contexts; the full が sounds a bit more careful.

What exactly is 早起き, and how is it different from 早く起きる?

早起き is a noun/する-verb meaning “getting up early.” It behaves like a noun: 早起きをする, 早起きができる.
早く起きる is a verb phrase: adverb 早く + verb 起きる = “to get up early” (one act).

• 早起きができるようになった: focuses on ability to perform the activity.
• 早く起きられるようになった: uses the potential of 起きる, focusing on that action.
• 早起きするようになった: emphasizes a new habit/regular behavior.
