Forms

mijar (first-person singular present mijo, first-person singular preterite mijei, past participle mijado)[1] Old Galician-Portuguese wrote meiar and mejar.[2][3] Houaiss records meijar in 1611, and Feijó (1734) still gives meijar beside mijar.[4][5]

Etymology

It is inherited from Late Latin meiō (“to urinate”), the classical Latin verb moved from the third conjugation to the first.[4][2][6][1] The oldest texts write Old Galician-Portuguese mejar and Old Galician-Portuguese meiar.[2][3] The first-conjugation form is recorded from the 4th century in several Latin grammarians, among them Diomedes and Priscian.[7][8] Nascentes notes that the move of the verb into the first conjugation has not been explained, and cites an older view that the vowel /i/ of the first syllable is due to the following palatal sound.[8]

The same Latin verb is Galician mexar, Asturian mexar, Spanish mear, Sardinian meare and Dalmatian miur.[9][10][1] Corominas observes that the other Romance languages, from Romanian to Catalan, preferred instead a type *pissiō of imitative origin.[7]

The Latin verb goes back to *meiɣjō and *h₃meyǵʰ- (“to urinate”).[1][11] Its cognates include Ancient Greek ὀμείχω (omeíkhō), Sanskrit मेहति (méhati) and Old Norse míga.[1][11]

Earliest recorded meaning

The verb appears in the 13th century in two cantigas d'escarnho of Afonso X: que lhi mejasse “that he should piss on him” and Med' ei do pertigueiro tal que mejo “I am so afraid of the verger that I piss myself”.[2][3][12] The second line already joins the verb to fear, a sense the dictionaries record much later.[3]

Semantic evolution

The dictionaries from 1697 on give the plain sense “to urinate” and translate it with the Latin verb.[13][14] Bluteau lists mijar na cama “to wet the bed” and the reflexive mijar-se.[14] Morais (1813) adds mijar-se de medo “to be very afraid”, and Caldas Aulete the slang mijar ossos “to give birth”.[15][16] Houaiss lists the extended sense “to let out any liquid” and “to scold harshly”, and Michaelis “to treat with contempt”.[4][17] In Brazil mijar para trás means to go back on one's word.[18][16]
