Phlegm is stuck in my throat and it's annoying me.
I am studying Japanese, but I am in trouble because I don't understand the meanings of nouns, particles, and so on.
"Why don’t you stay open later?" "Sorry, it’s not really my call. I just work here."
This word consists of kanji with hiragana attached. Because the hiragana ends with an う sound, you know this word is a verb. The kanji itself means distressed and troubled. The verb versions of those are to be distressed and to be troubled.
If someone seems to be distressed maybe someone they know is in a coma (こま). Not too many things are more distressing and troubling than that.
