Awhile means “for a short time.” It is one word, and it works like an adverb: it tells you how long something goes on. Sit awhile. We talked awhile.

Awhile Awhile means "for a short time." 意思是「一會兒、短時間」。It is one word 它是一個字, and it works like an adverb 用法像副詞: it tells you how long something goes on 告訴你一件事持續多久。Sit awhile. 「Sit awhile.」（坐一會兒）。We talked awhile. 「We talked awhile.」（我們聊了一會兒）

You do not put for in front of it, because that “for” is already built into the word. The stretch of time is short in a human, loose way — a few minutes, perhaps a little longer — not a year, and not a time you would set on a clock.

You do not put for in front of it 前面不加for, because that "for" is already built into the word 因為那個「for」的意思已經內建在這個字裡面了。The stretch of time 這段時間的長度 is short in a human, loose way 是一種人感覺上、鬆散的「短」 — a few minutes, perhaps a little longer 幾分鐘，也許再久一點 — not a year 不是一年, and not a time you would set on a clock 也不是你會用時鐘去設定的時間

Though actually many native speakers write a while as two words even when they mean this, and in speech you cannot hear any difference at all. Careful writing still keeps awhile for the adverb, and a while for the noun meaning “a period of time,” which can take for: stay for a while.

Though actually 不過其實, many native speakers 很多母語人士 write a while as two words 會把它寫成兩個字a while even when they mean this 就算他們想表達的是這個意思, and in speech you cannot hear any difference at all 而在說話的時候你根本聽不出差別。Careful writing 講究的寫作 still keeps awhile for the adverb 還是把awhile留給副詞用, and a while for the noun meaning "a period of time," 把a while留給名詞，意思是「一段時間」 which can take for 這個名詞可以搭配for: stay for a while 「stay for a while」
