Forms

transformar (first-person singular present transformo, first-person singular preterite transformé, past participle transformado)[1] Nebrija has the form without ⟨n⟩, trasformar, and the Academy's dictionaries of 1843 and 1846 refer transformar to it;[2][3][4] Moliner still lists trasformar as a less frequent variant.[5][2][3][4]

Etymology

It is borrowed from Latin trānsfōrmō (“to change in shape, transform”), a learned word first found in Berceo in the 13th century.[5][6][7][1] The verb is formed from Latin trāns- (“across, beyond”) + fōrmō (“to shape, form”),[8][1] and its second part is the verb of fōrma (“form, shape”), the source of Spanish formar.[9][7] Corominas treats it in his article on the noun.[5]

The same Latin verb was borrowed as Portuguese transformar in the 14th century,[10] as Catalan transformar[11] and as French transformer, a learned remodelling of about 1300 of the older Old French tresformer.[12]

Earliest recorded meaning

Berceo's Milagros de Nuestra Señora (dated 1246–1252 in the CDH, known from an 18th-century copy) tells how the devil took the shape of an angel: Transformóse el falso en ángel verdadero “the false one turned himself into a true angel”.[13][14] The word is reflexive there, “to change one's shape”.[13]

Semantic evolution

In the 13th century the Calila e Dimna has la rata transformada en niña “the rat changed into a girl”,[13] and Alfonso X's General Estoria uses the verb both for changing the form of a person or thing and for changing someone's conduct or habits.[15] The verb remained a word of learned and poetic texts in the 15th century, in the cancioneros and in Villena's version of the Aeneid.[13]

The Diccionario de Autoridades adds a sense from the language of love and mysticism: to enter so far into someone's affection that one seems turned into the beloved.[16] Terreros gives the figurative sense of a person changing appearance so as not to be recognised.[17] The Academy defined the reflexive as “to change one's bearing or habits” in 1869,[18] and in 1899 it split the senses into changing the form of a person or thing, turning one thing into another, and changing someone's bearing or habits.[19] The DLE adds a sports sense, scoring from a free kick or penalty in rugby, basketball or football, and the electrical sense of changing the voltage of a current.[20] Moliner notes its frequent use for the processing of raw materials in industry.[4]
