## AI Etymology
acerb comes from Latin acerbus ('bitter, sharp, harsh'), from acer ('sharp, keen'), ultimately from Proto-Indo-European *h2eḱ- ('sharp, pointed'). The path is chiefly one of transmission: an older form is taken into English, with the word's shape and meaning carried through the language names and forms preserved in the history. In modern use, the adjective sense is "sharp and bitter in taste, manner, or speech", which keeps the etymology connected to the word's present dictionary value rather than treating it as a merely historical label. The wider word family includes related English forms such as acerbic, acerbity, exacerbate and derivatives such as acerbic, acerbity, showing how the same base continues to support neighboring English vocabulary. The principal historical forms in the chain include Latin acerbus, Proto-Indo-European *h₂eḱ-, which anchor the explanation in named linguistic material.
