Forms

croiser[1] Old French cruisier (about 1100); croiser from the 12th century.[2][3]

Etymology

It is formed from French croix + -er (Old French crois),[4][3][1][5] from Latin crux (“cross”), through its accusative.[6]

Compare Old Occitan crozar, Catalan crusar, Spanish cruzar, Portuguese cruzar and Italian crociare.[7][8][1]

Earliest recorded meaning

The Chanson de Roland (about 1100) has cruisier “to lay crosswise”: Cruisiedes ad ses blanches mains les beles (“he has crossed his fair white hands”).[4][7]

Semantic evolution

In the time of the crusades, long before the word croisade, soi cruisier meant “to take the cross”, to sew a cross on one's garment and vow to go on crusade (1174, Guernes de Pont-Sainte-Maxence), and a croisé was a crusader (12th century).[4][9]

Se croiser “to meet going in opposite directions” is in Froissart (second half of the 14th century), and Aubigné has croiser le chemin à quelqu'un (1620).[4][9] The sense “to cut across (a line, a road)” dates from 1660 (Oudin).[2][10] In the navy (1671, Pomey) a ship croise when it sails to and fro in given waters to watch them, hence croisière (1680) and the modern croiseur “cruiser” (1690).[4][9][6] The breeders' sense “to cross (animals)” appears before 1782 (Raynal), croiser le fer in fencing in 1835.[4][9][10] Se croiser les bras has taken the figurative sense “to do nothing”.[9][2]
