Recently I was listing a youtube video and I found a song that blew my mind. I can understand almost every word, but no matter how hard I try, I can't understand the construction: 覚えちゃうくらいの距離で. If you could, explain me the use of ちゃう and くらい because I think the definitions I have of them are not correct. I really appreciate any help you can give to me. Thank you!


キミの体温感じてる いつも口ずさむあのメロディー
覚えちゃうくらいのキョリで 同じごはん食べてても
どうしてこうも違うのかな 今は何考えてるの?

ねえ早く帰ってきて My Sweet Prince

ふたりのセカイ ふたりのミライ

溢れる想い 溺れそうになったら

いつかおそろいで買った 色違いのクッション抱いて
寝てるキミを抱きしめる ベッドははんぶんこ
ずっとぎゅっとくっついてたら 同じ夢まで見ちゃうかもね

「このセカイがずっとずっと続きますように」 願うの

思うだけじゃ伝わらなくて 声に出さないとわからなくて
もどかしくて わかってほしくて 無理しちゃって ケンカもして
離れてって 寂しくて 苦しくって 泣いちゃって
それでもずっと一緒にいたいの 好きだから

ふたりのセカイ ふたりのミライ

溢れる想い 溺れそうになったら


  • Are you sure "覚えちゃうくらいの距離で" is correct? I don't see those lyrics anywhere online. I could try to explain like that but it would be best if you give more context (a few lines before it and after).

覚えちゃう is short form of 覚えてしまう, where 〜てしまう means something is funny, exaggerated, accidental, or some other type of emphasis.

くらい here means "the amount" or "to the extent"

UPDATE: The explanation I had here was wrong, which was pointed about by user naruto. So I am re-writing it based on his suggestion which I agree with.

Here 覚える simply means "to remember" or even "memorize", and the connotation is that the melody referred to in the previous line is at such a distance (= so close) that the person hearing it will memorize it.


Literal: At a distance such that I remember it

Non-literal (but more natural): So close that it sticks in my head

  • Ok, you are translating 距離 as close? I thought it means distance or far I did not know it also means close. Am I correct?.

  • Yes, 距離 is literally "distance", but I translated "close" because it is implied here. I just edited my post significantly, please check out the result.
