IPA: /ˈfɪstfəl/
KK: /ˈfɪstfəl/
The quantity of something that can be held in a person's closed hand.
He grabbed a fistful of sand and let it slip through his fingers.
Fistful → It is formed from "fist" (from Old English "fist", meaning a hand with fingers curled) and "-ful" (meaning full of). The word "fistful" means full of or as much as can be held in a fist.
Think of a 'fist' being 'full of' something — that's what a fistful means.
