IPA: /ˈkæn.fəl/
KK: /ˈkænˌfʊl/
The amount that a can can hold, often used to measure liquids or other substances.
I filled the canful of water and carried it to the garden.
Canful → It is formed from "can" (from Old English "canne", meaning a container for liquids) and "-ful" (meaning full of). The word "canful" means the amount that a can can hold, or full of what a can contains.
Think of a 'can' as a container and '-ful' meaning full of — so a 'canful' is the amount that fills a can.
