Pronunciation

  • IPA (Classical): [aˈkɛr.bʊs][1]
  • IPA (Ecclesiastical): [aˈt͡ʃɛr.bus][1]

Forms

acerbus (feminine acerba, neuter acerbum, comparative acerbior, superlative acerbissimus, adverb acerbē); first/second-declension adjective[1]

Etymology

It is from Proto-Italic *akri-þo- (“having sharpness”) or *akro-þo-, from the root Proto-Indo-European *h₂eḱ- (“sharp”) of ācer “sharp”.[2][1][3] Nussbaum sees in it the same suffix that elsewhere gives Latin -idus.[2][1] Lewis & Short compare superbus beside super.[4]

Earliest recorded meaning

De Vaan dates it from Plautus.[2][5] Köbler dates Plautus c. 250–184 BC.[6]

Semantic evolution

It meant sour, bitter or harsh to the taste, as the sea is acerbus in Lucretius, and of fruit unripe or green, as Cato's oil from the greenest olives.[3] Figuratively it was said of people who are hostile or pitiless, of a death that comes too early, of feelings that are keen or bitter, of grievous events and pains, and of strict or morose people.[3]

In medieval glosses it was also a crab apple.[7] English acerbic was taken from it in 1865, and exacerbō “to make bitter” gave English exacerbate in the 1650s.[8] It was borrowed into Italian acerbo and French acerbe.[1]
