Forms

cagar (first-person singular present cago, first-person singular preterite caguei, past participle cagado)[1]

Etymology

It is inherited from Latin cacō (“to defecate”), written Old Galician-Portuguese cagar in the oldest texts.[2][3][1] Cunha calls the Latin verb a word of expressive formation.[3]

The same Latin verb is Galician cagar, Spanish cagar, Catalan cagar, Occitan cagar, French chier, Italian cacare and Romanian căca.[4][5][1]

De Vaan reconstructs Proto-Italic *kak(k)- and compares κακκάω (kakkáō, “to defecate”) and какать (kakatʹ); he takes the verb for a nursery word or an imitation of the sound, and thinks the Germanic verbs such as kacken may have been borrowed from Latin.[6] Wiktionary sets up a root *kakka-.[1]

Earliest recorded meaning

Houaiss and Cunha date the verb to the 13th century.[2][3] Lorenzo's chronology quotes a cantiga of King Denis about a sick man who con medo per ssy caga “soils himself with fear”, already the figurative use of the reflexive verb.[7][8]

Semantic evolution

The dictionaries of the 16th and 17th centuries gloss the verb only with its Latin equivalents: Cardoso (1569) with caco and purgare alvum, Barbosa (1611) also with the participle cagado.[9][10] Morais (1813) adds the reflexive cagar-se “to soil oneself” and labels the word impolite.[11] Vieira calls it a low word and records a transferred transitive use, to utter maxims or rhetoric.[12] The original Caldas Aulete warns that the verb and many of its derivatives are indecent and kept out of polite conversation.[13]

Cunha dates the derivatives cagalhão and caganeira to 1844 and cagaço “fear” to 1873.[3] In Brazil the verb also means to be lucky, to botch a piece of work or spoil a plan, and not to care at all about someone or something.[2][14][15]
