A dog-end is the small leftover of a cigarette after someone has smoked it — the stub, often with a bit of ash, that gets dropped or put out.

A dog-end is是 after someone has smoked it有人抽完之後 a cigarette一根香菸 the small leftover of剩下的那一小截 — the stub菸頭， often with a bit of ash常帶著一點菸灰， that gets dropped or put out被丟掉或捻熄。

This is British informal speech, a bit rough, the kind of word you hear in the street or in older writing about pubs and pavements, not in a careful school essay. American speakers are more likely to say butt.

This這 is British informal speech是英式的口語， a bit rough有點粗， the kind of word是那種 in the street你會在街上、 or in older writing about pubs and pavements或在寫酒館和人行道的較舊文字裡 you hear聽到的字， not in a careful school essay不會出現在認真的學校作文裡。American speakers說美式英語的人 are more likely to say比較可能說 butt。

Though actually, even in Britain many people now just say stub or cigarette end; dog-end feels a little dated, and it can sound dirty because it names something thrown away. It is only this leftover, not the whole cigarette, and not a dog’s bottom.

Though actually不過其實， even in Britain就連在英國， many people很多人 now現在 just say也只說 stub 或 cigarette end； dog-end feels a little dated感覺有點過時， and it而且它 because it names something thrown away因為指的是被丟掉的東西， can sound dirty聽起來可能有點髒。It它 is only只指 this leftover這截剩下的， not the whole cigarette不是整根菸， and not也不是 a dog’s bottom狗的屁股。
