Forms

usar (first-person singular present uso, first-person singular preterite usei, past participle usado)[1] Old Galician-Portuguese wrote usar, ussar and husar;[2][3] Houaiss records husarmos and uzar in the 14th century.[2][3]

Etymology

It is inherited from Vulgar Latin *ūsō (“to use”), written Old Galician-Portuguese usar in the oldest texts.[2][4][1] The Latin verb is a frequentative of ūtor (“to use”), formed on its past participle ūsus.[2][4][5][1] Houaiss, Cunha and Aurélio give it as a reconstructed form; it is recorded in Medieval Latin from the 8th century, and Niermeyer has it in the senses “to observe (a custom)”, “to enjoy (a thing)” and “to wear out”.[2][4][6][1][7] The DLP derives the Portuguese verb from uso with the suffix -ar instead.[8]

The same Latin verb is Spanish usar, Catalan usar, French user and Italian usare.[9][10][11] The deponent verb goes back to *oitōr, perhaps from *h₃eyt- (“to take along, fetch”).[1][12]

Earliest recorded meaning

The first records are in Galician-Portuguese notarial documents: Maria Rodriguez ussa contenda con o abbade “Maria Rodriguez is pursuing a dispute with the abbot” (1253–1254), and que o usarõ en tempo del Rey don Alfonso “that they practised it in the time of King Alfonso” (1258–1261).[3] The sense there is “to practise, exercise, hold”.[3]

Semantic evolution

In the 13th century the verb already meant both “to be accustomed to” and “to use, employ”: the Cantigas de Santa Maria have mui gran tenp'aquest'usou “he did this for a very long time” and usou esta oraçon “he used this prayer”, and in a cantiga d'escarnho an old cape tan muito s'usou “has been worn so much”.[3][13] Houaiss notes that Cunha's medieval index also has the 14th-century senses “to exercise”, “to have dealings with”, “to devote oneself to”, “to enjoy” and “to grow accustomed”, now obsolete.[2] The sense “to wear (clothes, a beard)” and “to wear out by use” are in Morais (1813) and the original Aulete.[14][15]

Houaiss and Aurélio still give “to be in the habit of” (usava jantar cedo “he used to dine early”) as a current sense, while Wiktionary labels the construction with an infinitive archaic or dialectal.[2][6][1]
