Forms

étui m (plural étuis)[1] Old French estui,[2][3] Middle French estuy;[4] the spelling étui dates from the 17th century.[5]

Etymology

It is inherited from Old French estui, a deverbal noun from Old French estuier (“to keep, store”) (also estoiier), a verb of the 12th century still in use in the 16th.[2][3][6] The origin of the verb is obscure.[2][6] The TLFi, the FEW, Bloch and Wartburg and the Grand Robert tentatively derive it from Vulgar Latin *studiō (“to take care of”), from Latin studium (“zeal, care”) (whence étude), a verb recorded in Medieval Latin in the sense "to look after, keep in good order" and continued in many Italian dialects.[2][7][6][8] Pierre Guiraud instead proposed *extuicō, from tueor (“to watch over, protect”).[3] Diez, followed by Littré, linked it with Middle High German stūche (“a kind of sheath”), and Wiktionary considers a Germanic origin more likely.[4][1]

Compare Occitan estug, Catalan estoig, Spanish estuche, Portuguese estojo and Italian astuccio.[1][4]

Earliest recorded meaning

It is first found about 1170 in the Livre des Rois in the phrase garder en estui “to put away, store”, used of weapons.[2][4]

Semantic evolution

In Old French estui also meant a prison, a place where someone is kept (about 1190),[3][5][6] and then a hollow object used as a container, the sense that lasted.[3] From about 1550 it also meant a narrow place in which one is shut up, a sense now gone, and the figurative visage à étui (1752) was a very ugly face, one to be hidden in a case.[3][4]

The general sense of “container” spread to many fields: the cartridge case (1836), étui à voiles in the navy (1866), the penis sheath of ethnology (20th century), and by likeness of function the sheath of an insect's sting (1865), the word having earlier meant an insect's wing case.[3]
