Pronunciation

Forms

mulo m (plural mulos, feminine mula, feminine plural mulas)[1] The feminine mula is the older word in texts: it is first recorded in the Cantar de mio Cid (c. 1140).[2][3]

Etymology

It is inherited from Latin mūlus (“mule”); the feminine mula is inherited from Latin mūla (“she-mule”).[4][2][3][1] The Spanish Wiktionary takes the masculine instead as formed from the feminine with the ending -o.[5] From the beginning of the 17th century macho tended to replace the word, which nevertheless survived in literature and, for example, in the language of military administration.[2] In this sense the replacement is probably from Portuguese, ultimately from the Old Portuguese word for the mule.[6]

The same Latin words are Portuguese mu and mula, Catalan mul and mula, Italian mulo, Occitan mul and French mule.[7][8]

The Latin noun goes back to Proto-Italic *musklo- or *mukslo-.[9] Its cognates are Ancient Greek μύκλος (múklos) and the Hesychian gloss μυχλός (mukhlós), Albanian mushk and Old East Slavic мъскъ (mŭskŭ); de Vaan takes the word to be a loan that entered Europe from Asia Minor.[9][1] Gómez de Silva also considers it probably not Indo-European.[10]

Earliest recorded meaning

Corominas dates the first record to a charter of 1042 in Oelschläger's list; the word then appears in the Fuero de Madrid (1158–1202) and in the glossaries of Toledo and El Escorial of about 1400.[2][3][11] The feminine mula is in the Cantar de mio Cid, the Libro de Apolonio, the Calila and Juan Ruiz.[2]

Semantic evolution

Covarrubias in 1611 defines the mule as the sterile offspring of horse and she-ass or of ass and mare, and notes that a large mule for a litter or for loads was called acémila.[12] The Academy's 1817 edition records the proverb mulo cojo e hijo bobo lo sufren todo “a lame mule and a foolish son put up with everything”, said of the least valued being given the most work.[13] From 1843 it defined the word with both genders, mulo, la.[14]

The mule's hybrid birth gave mulato (1525), and muleta “young she-mule” (1495) became “crutch” (1570), which carries the lame as a mule its rider.[3][2] Colloquially a mulo is a strong, tireless person.[4][15] The feminine has gained senses of its own: “a lie” in Argentina and Uruguay, and a person who smuggles small amounts of drugs.[4][16] In Panama, Colombia and Ecuador mula is a large lorry.[17] In the Canaries Viera y Clavijo used mulo for the sterile worker bee or wasp.[18]
