Middle English, Old English -full, -ful, representing full, ful full1 Usage note
The plurals of nouns ending in -ful are usually formed by adding -s to the suffix: two cupfuls; two scant teaspoonfuls. Perhaps influenced by the phrase in which a noun is followed by the adjective full ( both arms full of packages ), some speakers and writers pluralize such nouns by adding -s before the suffix: two cupsful.
