Pronunciation

Forms

muid m (plural muids)[1] Old French mui; the spelling with an etymological ⟨d⟩ is found from the end of the 16th century.[2][3] The Grand Robert and the GLLF date muid to about 1380, in the Aalma.[4][5] In muid the ⟨d⟩ is silent and not pronounced in liaison.[6]

Etymology

It is inherited from Old French mui, inherited from Latin modius (“a measure of capacity, chiefly for grain”).[2][3][7] The Latin word also named, in sailors' language, the socket for the foot of a mast, and is the source of moyeu.[3] Rey connects it with the Indo-European root also behind mode and moule1.[3]

Cognate with Walloon moie, Old Occitan muei, Italian moggio and Portuguese modio.[6]

Earliest recorded meaning

It is first found about 1135 in the Couronnement de Louis, meaning a cask or barrel: Ge te dorrai un grand mui de deniers “I will give you a great barrel of pennies”.[2]

Semantic evolution

The measure of capacity is recorded about 1160, in the Roman d'Énéas.[2] The muid measured liquids, grain, salt and other dry goods, and its size varied with the region and the goods.[2][5] From the measure came muid de terre, the area of land that a muid of seed would sow, recorded about 1283 in Beaumanoir.[5]

The sense “cask holding a muid”, older than the measure, has outlasted it.[3] The derivative demi-muid was formed in the 16th century.[3]
