brusque

the english word 'brusque' was borrowed in the 17th century from the french 'brusque', meaning 'lively, fierce'. the french term derived from the italian 'brusco', which meant 'sour, sharp', a sense used to describe unripe fruit. the italian word, in turn, traces its origin to the medieval latin 'bruscus', referring to butcher's broom, a shrub with sharp, stiff leaves. the semantic journey moved from the physical description of a prickly plant to a metaphorical characterization of a sharp, abrupt, and unceremonious manner in human interaction.

this word is a loanword adopted as a single unit from french. it is not productively segmented using english morphemes.
