IPA: /ˈsmɔːlˌsɔːrd/
KK: /ˈsmɔːlˌsɔrd/
A type of light sword that is designed mainly for thrusting, often used in dueling and by civilians in the past, particularly during the eighteenth century.
He practiced his fencing skills with a smallsword, mastering the art of thrusting.
Small sword is formed from "small" (from Old English *smae, meaning little or not large*) and "sword" (from Old English *sweord, meaning a cutting or thrusting weapon*). The term "smallsword" refers to a type of sword that is smaller and lighter than traditional swords, designed for thrusting rather than cutting.
Think of a 'little' ('small') cutting weapon ('sword') — that's what a smallsword is, a smaller version of a sword.
