Forms

bât m (plural bâts)[1] Old and Middle French bast; the spelling bât is late, from 1740.[2]

Etymology

It is inherited from Old French bast, inherited from Vulgar Latin *bastum (“that which carries”), a verbal noun from *bastō (“to carry”).[3][2][4][5] Wiktionary and the GLLF trace the Vulgar Latin verb to Ancient Greek βαστάζω (bastázō, “to lift, bear”).[1][6] The Grand Robert and the Petit Robert also cite Guiraud's proposal of a popular Latin *basitō, from Latin basis (“base, support”).[7][8]

The word spread from the Mediterranean regions northwards, where it displaced somme2 (kept in bête de somme), the older northern word for a packsaddle; the Classical Latin clītellae disappeared everywhere.[3][2][4] Bloch and Wartburg note that the new terms came from Greek or Arabic, from regions where pack animals were used more.[4]

Cognate with Italian basto, Spanish basto and Old Occitan bast.[4][9]

Earliest recorded meaning

It is first found in the 13th century in the trade regulations of the Livre des métiers, where a horse carrying goods en bast owes a toll, in the sense of a packsaddle.[3][9]

Semantic evolution

The word has kept its concrete sense of a frame strapped on a pack animal's back.[2] By metaphor it stands for a burden or constraint, above all in the phrase c'est là que le bât blesse “that is where the trouble lies”, found as le bast m'en blesse about 1357 and in the Farce de Maître Pathelin (1464).[3][2]

Cheval de bât (1740) was said first of a dull, stupid man and later of a man who does the heavy chores; the phrase has since gone out of use.[2][3][9] The derivatives date from Middle French: bâtier (before 1292), bâter (1549), embâter and débâter (15th century).[2][4]
