I came across this phrase while playing a Japanese game:
ダメだわ、全然食欲がわかないわ……
I was just wondering what does 食欲がわかない mean in this context, furthermore, I want to know about what Kanji is わかない.
Appreciate the help!
食欲がわく literally means "appetite springs up (in one's mind/heart)" → "have a good appetite", "feel hungry" or "feel like eating". The わく here is like "spring up", close to 生じる or 出る.
わく in the phrase 食欲がわく should be 湧く (rather than 沸く, "to boil") in Kanji, but it's usually written in Hiragana.
A few examples of this わく(湧く) from プログレッシブ和英中辞典:
わく【湧く】
Ⅱ〔心の中に起こる〕
あなたの話を聞いて勇気[希望]がわいた。
Your words have filled me with courage [hope]. / What you said has given me courage [hope].
恐怖心が湧いた。 Fear sprang up in 「my heart [me].
見る物すべてに興味がわいた。 I took interest in everything I saw.
それには全く好奇心がわかなかった。 It failed to excite my curiosity.
I found this: https://eow.alc.co.jp/search?q=%E9%A3%9F%E6%AC%B2%E3%81%8C%E3%82%8F%E3%81%8F
Which says it means to work up one's appetite
And I found this: https://eow.alc.co.jp/search?q=%E9%A3%9F%E6%AC%B2%E3%81%8C%E3%82%8F%E3%81%8F
For what the Kanji might be: 湧{わ}く
Does "I can't work up an appetite" make sense in the context of your game?
