IPA: /ˈlæp.fəl/
KK: /ˈlæpˌfʊl/
The amount that can be held in someone's lap, often referring to a quantity of something like food or items.
She carried a lapful of flowers back from the garden.
Lapful → It is formed from "lap" (from Old English *læppa*, meaning the front part of the body between the waist and knees) and "-ful" (meaning full of). The word "lapful" means a quantity that can be held in one's lap, or full of lap.
Think of the 'lap' as the area in front of you that can hold things, and '-ful' means full of — so a lapful is something that fills that space.
