Etymology: The name is a chemist's assembly of pieces, and its core part, "spiro-", traces back to a Proto-Indo-European root meaning to coil or wind. That root passed through ancient Greek "speira", meaning a coil or ring, which Latin took as "spira". In chemistry, "spiro-" names a type of molecule in which two rings share a single atom, and the coiled sense of the Greek root suits that twisted arrangement. The rest of the name is a stack of chemical suffixes. "Lactone" is a ring-shaped ester, built from "lact-", from Latin "lac" meaning milk, plus "-one", the suffix used for ketones. The linking "-o-" is a joining vowel that glues the parts together. The drug therefore takes its name from its molecular architecture rather than from any medical purpose, which is why the name looks so unlike the common words it sits beside.

Synonyms: aldactone, diuretic
