Pronunciation

  • Classical: [ĩːˈsʊɫ.sʊs][1]
  • Ecclesiastical: [inˈsul.sus][1]

Forms

īnsulsus (feminine īnsulsa, neuter īnsulsum, comparative insulsior, adverb īnsulsē); first/second-declension adjective[1] The comparative īnsulsior is in Jerome.[2]

Etymology

It is from Latin in- (“not”) + salsus (“salted, witty”),[3][4][1] from the root of sāl (“salt, wit”).[5] The ancient grammarians already explained it as formed from salsus.[4]

Earliest recorded meaning

Plautus says of a man that he has no dull wit, non insulsum huic ingenium.[3] Köbler dates it from Catullus.[5]

Semantic evolution

Its literal sense is unsalted: Columella has unsalted olive lees.[3][2] Cicero speaks of an appetite for tasteless food.[2] Figuratively, as salsus also meant witty, it means witless, dull or stupid, of people and of actions or style:[3][2][1] Cicero says that a not tasteless kind of joke can lie in a single word.[3] It also means bungling or awkward.[2][1] Church Latin has it as tasteless, insipid, and silly, absurd or awkward.[6]
