A joke that lands flat, a comedian nobody laughs at, a friend's 'joke' about your weight — those are unfunny.

So the word carries a small judgement: someone reached for a laugh and missed. That is why it feels harsher than "not funny." "Your joke wasn't funny" is a report. "Your joke was unfunny" is a verdict, and people hear the disapproval in it.

so the word carries a small judgement所以這個字帶著一點評價的意味：someone reached for a laugh and missed有人想博君一笑，卻沒能成功；that is why it feels harsher than "not funny"這就是為什麼它聽起來比「not funny」更重；"your joke wasn't funny" is a report「你的笑話不好笑」只是在陳述事實；"your joke was unfunny" is a verdict「你的笑話很 unfunny」則像是在下判斷，and people hear the disapproval in it聽的人會聽出裡面的不認同。

It is casual, common in reviews and online comments, and slightly more common in writing than in speech, where most people just say "that wasn't funny."
