Thimbleful

Part of speech: noun

Definitions

1. A tiny amount of liquid, just enough to fill the bottom of a thimble ; a small quantity of anything, poured or measured out in a minimal portion
2. The smallest drop or splash of a drink, barely covering the bottom of a container ; a slight measure of any substance or thing given in very small amounts
3. A minute quantity of a liquid, scarcely more than a dab ; a modest little portion of any material, offered in only a trace amount

Etymology: A thimble was originally a cloth-covering or protective cap of a sort rather than the small metal cup we know today, and "thimbleful" is simply the amount such a cup could hold, built by adding the suffix "-ful" (as in "spoonful" or "handful") to "thimble." The pattern is ordinary: "-ful" attaches to a noun to name the quantity that fills a container or hand, so the word gives a measure of volume through the thimble's small size. The word is a plain compound with no notable coinage story, and the first recorded use is not documented in the source, so there is no particular author or work to credit. Its meaning stays literal: a very small quantity, roughly the contents of a thimble, used both for actual measures of liquid and figuratively for a small amount of anything.
