IPA: /əˈwaɪl/
KK: /əˈwaɪl/
For a short period of time.
Please wait here awhile while I finish my work.
Awhile → The word is formed from "a-" (a variant of "on" or "in") and "while" (from Old English "hwila", meaning a period of time). The term "awhile" means for a period of time or for a short duration.
Think of being 'in' ('a-') a 'period of time' ('while') — that's why awhile means for a short time.
