Forms

cansar (first-person singular present canso, first-person singular preterite cansei, past participle cansado)[1] Old Galician-Portuguese wrote canssar (13th century), later also cãssar (14th century).[2][3] The spelling cançar, cançaço was common in the 19th century, though Vieira held that ⟨s⟩ was correct.[4]

Etymology

It is probably inherited from Latin campsō (“to sail round, to double a cape”), a word of the language of sailors.[2][3][1] The Latin verb is from Ancient Greek κάμψαι (kámpsai), the aorist of κάμπτω (kámptō, “to bend”).[1][5] Corominas, followed by Houaiss and Nascentes, gets from the nautical “to double a cape” to “to tire” through the idea “to cease doing something”.[2][6] García de Diego sees the step as “to keep going round and round”, whose effect is tiredness, and notes that in the 13th century the verb meant “to grow tired”.[7] Latin glosses render the verb with “bends”.[7][8]

Diez, Adolfo Coelho and Meyer-Lübke derived the verb from quassō (“to shake, to shatter”), comparing alquebrar “to break one's strength”.[9][10] Meyer-Lübke rejected the Latin sailor's word because of its meaning.[11] Vieira, Figueiredo and the first Aulete still give this etymology.[4][12] Against it, Corominas and García de Diego point out that it cannot explain the /n/ before the /s/.[6][7]

The same word is Galician cansar and Spanish cansar, and the Latin verb also gave Italian cansare (“to move aside, to avoid”).[11][1]

Earliest recorded meaning

In a cantiga of Johan Baveca the word describes fighters tiring as they strike: e, dando colbes en vós, cansarán, “and, dealing blows on you, they will tire”.[13][14] Martin Soarez has se canssar ou sse caer, “if he tires or falls”.[14] The Crónica Geral uses it in the sense “to cease”: o muy noble rrey nõ quiso cansar de fazer bem, “the most noble king would not stop doing good”.[14]

Semantic evolution

The sense “to cease, to stop” of the Crónica Geral lives on in não se cansar de “never to tire of”.[14][2] The figurative “to bore, to weary” is recorded by the first Aulete and by Figueiredo.[15][12] Brazilian usage has a sense “to run short, to be lacking”: money never cansa for someone who always has it.[2][16] The reflexive also means “to take pains, to strive”.[2]
