Forms

besaiguë f (plural besaiguës)[1] Old French besagüe (1160), biesagüe (before 1188) and besague.[2][3][4] Also bisaiguë, recorded from the 18th century.[5][2]

Etymology

It is inherited from Vulgar Latin *bisacuta (“twice sharp”), the feminine of bisacūtus taken as a noun, short for ascia bisacuta (“double-edged adze”).[6][2][3][4][7] The Latin noun is found as a feminine noun meaning “axe” in Medieval Latin of the 9th and 10th centuries.[2][3] It is formed from bis (“twice”) and acūtus (“sharp”), and its sounds developed in the same way as those of aigu.[3][6][2]

Compare Italian bisacuto.[1] The form bisaiguë was influenced by Italian bisegolo (“double-edged tool”).[5]

Earliest recorded meaning

In Wace's Roman de Rou (1160) the carpenters carry great axes on their shoulders and besagües hanging at their sides, so the first sense is a carpenter's tool.[2][3]

Semantic evolution

Soon after, the word also named a medieval weapon, an axe with two opposite cutting edges: in Partonopeus de Blois (before 1188) a knight wears his biesagüe beside his dagger.[2][3] Rutebeuf in the 13th century compared people who are “double tools” to the besaguz, which cuts on both sides.[8] The weapon is now historical, while the carpenter's tool, sharpened at both ends, survives as a technical term.[3][6] In 1752 the Trévoux dictionary records a glazier's hammer of the same name.[2]

Claudel used hache besaiguë as an adjective in his 1896 translation of Aeschylus, which the TLFi takes as a calque of a Greek word for “double-edged”.[2]
