Spelling

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.

Usage

What does -ful mean? The suffix -ful means “full of,” “characterized by,” “tending to,” “able to,” or “as much as will fill.” It is often used in a variety of technical and everyday terms.
