formic

The word "formic" is a direct borrowing from the Latin adjective formicus, which itself derives from formica, the Latin word for "ant". The connection is literal and scientific; the term was first used in English in the late 18th century to describe the acid that was distilled from the bodies of ants. The suffix "-ic" is a standard adjectival ending, indicating a relationship or pertaining to. Thus, the word's logic is transparent: it literally means "pertaining to ants," a meaning that has been preserved in its specific chemical and zoological applications.
