Someone who talks far too much, especially someone who talks at length and importantly while saying very little of substance. The picture inside the word is a bag full of air: plenty of puff, no weight. This is an insult, and not a gentle one, but it is an old-fashioned, almost comic sort of insult — the kind of word an irritated older person uses about a politician, a preacher, a manager, or an uncle who has trapped everyone at the dinner table. It is not obscene and would not shock anyone, but you would never say it to the person's face in a formal setting.

Someone who talks far too much話講得太多的人，especially someone who talks at length and importantly while saying very little of substance尤其是長篇大論、講得煞有介事，內容卻沒什麼實質的人。The picture inside the word is a bag full of air這個字背後的畫面是一個裝滿空氣的袋子：plenty of puff, no weight鼓得很飽，卻沒有分量。This is an insult這是一種侮辱，and not a gentle one而且不是溫和的那種，but it is an old-fashioned, almost comic sort of insult但是是老派、近乎滑稽的那種侮辱——the kind of word an irritated older person uses是不耐煩的長輩會用的字，about a politician, a preacher, a manager, or an uncle who has trapped everyone at the dinner table用來說政客、傳道人、主管，或是在飯桌上纏著大家講不停的叔叔伯伯。It is not obscene and would not shock anyone它不算粗俗，不會讓人嚇一跳，but you would never say it to the person's face in a formal setting但在正式場合絕不會當面對人說。

Note what it does and does not mean. It is not simply 'chatty' or 'sociable' — a friend who talks a lot happily is not a windbag.

Note what it does注意它包含什麼意思，and does not mean又不包含什麼意思。It is not simply 'chatty' or 'sociable'它不只是'chatty'（愛聊天）或'sociable'（善於交際）——a friend who talks a lot happily is not a windbag一個開心話多的朋友並不是windbag。

The word carries the extra idea that the person believes their own speech is important, and that everyone else is waiting for them to stop. That is why it attaches so naturally to public speakers.

The word carries the extra idea這個字還帶著一層意思，that the person believes their own speech is important就是這個人相信自己講的話很重要，and that everyone else is waiting for them to stop而且大家都在等他講完。That is why it attaches so naturally to public speakers這就是為什麼它這麼自然地會用在公開演講的人身上。

The word 'wind' here means air, and there is a hint of the older sense of 'wind' as empty talk, as in 'that report is just wind'. Note the pronunciation: 'wind' as in air, /wɪnd/, not 'wind' as in wind a clock. It is a countable noun — a windbag, two windbags — and there is an adjective 'windy' that can mean long-winded in the same way, though 'long-winded' is the safer, more common way to say that a speech went on too long.

The word 'wind' here means air這裡的'wind'指的是空氣，and there is a hint of the older sense of 'wind' as empty talk也帶著'wind'古老意思裡「空話」的影子，as in 'that report is just wind'就像'that report is just wind'這種說法。Note the pronunciation注意發音：'wind' as in air, /wɪnd/這裡的'wind'唸/wɪnd/，跟「風」一樣，not 'wind' as in wind a clock不是'wind a clock'（上發條）那個'wind'。It is a countable noun這是可數名詞——a windbag, two windbags像'a windbag'、'two windbags'——and there is an adjective 'windy'也有形容詞'windy'，that can mean long-winded in the same way同樣可以表示長篇大論，though 'long-winded' is the safer, more common way to say that a speech went on too long不過要說一場演講講太久，用'long-winded'比較保險、也比較常見。
