Forms

callo m (plural callos)[1]

Etymology

It is inherited from Latin callum (“hard skin, callus”).[2][3][4][1] The Latin /ll/ became the palatal /ʎ/ written ⟨ll⟩, which in most of the Spanish-speaking world is now pronounced /ʝ/.[1] The same word is Portuguese calo, Galician calo, Catalan call and Italian callo.[5][6][7]

The Latin noun (also masculine callus) meant a hard substance: the flesh of animals or fruit, a hide, a scar.[8] De Vaan reconstructs Proto-Italic *kalno- (“hard”), perhaps first an adjective, which would explain the wavering gender and the verb calleō (“to be hard”); he compares Old Irish calath and Welsh caled (“hard”), but finds the Indo-European origin uncertain.[8] Wiktionary also proposes Proto-Indo-European *kal- (“hard”).[1]

Corominas defends the derivation of the sense “tripe” from the same word: the pieces of stomach eaten as tripe are the firmest and somewhat hard parts, not the thin ones that are thrown away.[2] He rejects a proposed origin in Italian caglio (“curdled milk”).[2][3]

Earliest recorded meaning

A literary man of 12th-century Zaragoza bore the Mozarabic nickname herraqállus “shoe-calluses”, which is the reason the BDELC dates the word to the 12th century.[2][3] The first record in a Spanish text is in the Libro de los caballos (c. 1275), in the sense “end of a horseshoe”: el callo de la ferradura.[9][10] Corominas's first record of the usual sense is the Gran conquista de Ultramar (c. 1295), of a man so devout that calluses grew on his knees.[2][11]

Semantic evolution

Covarrubias in 1611 defined the callus as hard rough skin made by work or rubbing, and recorded the figurative hazer callos en el trabajo “to grow hardened to work” and hazer callos en el vicio “to grow old in vice”.[12] He also noted the callo de herradura, a worn piece of a horseshoe from which strong tools were made.[12] The sense “tripe, pieces of the stomach of a cow or sheep eaten stewed” appears in Mateo Alemán's Guzmán de Alfarache (1599).[2][3] The Academy added the surgical sense, the scar that forms where the pieces of a broken bone join, in 1869.[13]

In colloquial Spanish of Spain callo is a very ugly person; the DRAE 2001 still restricted it to a woman.[4][14] The phrase dar el callo means to work hard.[15][1] In Mexico callo de hacha is the edible muscle of several bivalves, and in the Dominican Republic callo is an extremely tiresome person.[4][16]
