Etymology

In the sense “to patrol” the TLFi and the DHLF take it as a military specialization, in the 16th century, of the older verb of the same spelling “to handle messily, to paddle in mud”, which is a variant from French patouiller with an /ʁ/ taken from dialect words of similar sense such as gadrouiller and vadrouiller.[2][3][1][4][5] Etymonline likewise explains it as originally “tramp through the mud”, probably soldiers' slang.[6] The GLLF instead derives the military verb from the noun patrouille “patrol”.[7]

patouiller is formed on patte (“paw”).[8][6] Littré cites Picard patrouiller (“to walk in mud, stir water”), with a similar form from Champagne.[9]

Earliest recorded meaning

The TLFi dates the sense “to go on patrol” to 1553, in Le Plessis's translation of Aristotle's Ethics.[2][8] The verb itself appears in the early 15th century in the Quinze joies de mariage, meaning “to handle messily”.[2][9]

Semantic evolution

The noun patrouille, first (1538) “paddling, messing about” and a mop of old rags, took the sense “watch round by a military detachment” in 1559 under the influence of the verb, and later the detachment itself (1671).[3][2] The verb in this military sense later aged somewhat in favour of phrases built on the noun, faire une patrouille and aller en patrouille.[3] From 1903 (Larousse) it is also used by analogy of going back and forth in search of something.[7]

English patrol was taken from patrouille in the 1660s, and the English verb (1690s) partly from patrouiller.[6]

Usage notes

The older verb patrouiller “to paddle in mud, to splash about” and transitively “to handle messily, to paw at”, a synonym of patouiller, is listed as a separate headword by the TLFi and the GLLF and is now archaic or familiar.[2][7][9] Littré prescribed the pronunciation with a palatal ⟨ll⟩, not /j/.[9]
