Did you know?

If you’re the type of word nerd who finds poring over book glossaries to be the bee’s knees, we know you’ll get a buzz from this gloss of the verb gloss. To gloss something, such as a word or phrase, is to explain or define it. The noun gloss, it follows, refers to (among other things) a brief explanation of a word or expression. And a glossary of course is a collection of textual glosses, or of specialized terms, with their meanings. Both forms of gloss, as well as the word glossary, trace back to the Greek noun glôssa, meaning “tongue,” “language,” or “obscure word requiring explanation.” Another descendent of glôssa, the English noun glossa, refers not to a bee’s knees but to a bee’s tongue, or to the tongue of another insect.
