Etymology

The word “sharp” comes from Middle English scharp, from Old English sċearp, tracing back to Proto-Germanic *skarpaz and Proto-Indo-European *(s)ker-, meaning “to cut.” It has cognates in Dutch scherp, German scharf, and Danish skarp. Related words include Irish cearb (“keen; cutting”) and Latin acerbus (“tart, bitter”).

Pronunciation

In Received Pronunciation: /ʃɑːp/ (stress on the single syllable). In General American: /ʃɑːrp/. The “sh” sound is like in “ship,” followed by a short “a” as in “father,” and ends with a “p” sound. Rhymes with “carp” or “harp.”
