To bemoan something對某件事bemoan，is就是 to say you are sad or disappointed about it說你對這件事感到難過或失望，often常常 in a slightly heavy, complaining way帶點沉重、抱怨的口氣。You你 bemoan a loss會對一個損失bemoan，or或 bemoan the fact that things have changed對事情已經變了這個事實bemoan。

It is more formal than complain or moan, and you meet it in writing — news, essays, speeches — more than in chat. It can sound weary, and sometimes a little dramatic, depending on the speaker.

It它 is more formal than比 complain or moan（抱怨、發牢騷）更正式，and而 you meet it你會更常遇到它 in writing在書面裡——news新聞、essays文章、speeches演講——more than in chat而不是聊天裡。It它 can sound weary可能聽起來很疲憊，and而 sometimes a little dramatic有時候有點誇張，depending on the speaker要看說話的人。

You bemoan a thing directly: they bemoaned the delay, not bemoaned about the delay.

You你 bemoan a thing directly直接對一件事bemoan：they bemoaned the delay他們bemoan了這個延誤，not不是 bemoaned about the delay說bemoaned about the delay。

The old English word already meant to lament; today's shape matches be- (about, concerning) plus moan. The vowel in the middle lined itself up with moan over time.

The old English word古英文裡這個字 already meant to lament本來就是「哀嘆」的意思；today's shape現在的字形 matches對應著 be- (about, concerning)be-（關於）加上 plus moanmoan（呻吟）。The vowel in the middle中間那個母音 lined itself up with moan隨著時間跟moan對齊了 over time。
