Forms

ambiguo (feminine ambigua, masculine plural ambiguos, feminine plural ambiguas)[1] A form ambigo occurs in the 16th and 17th centuries (Balbuena rhymes it with amigo) and survives as a popular form in Chile.[2][3]

Etymology

It is borrowed from Latin ambiguus (“undecided, doubtful; of double meaning”).[4][5][6][1] The Latin adjective is formed on ambigō (“to be in dispute, to waver”) with the suffix -uus, and the verb on ambi- (“around, on both sides”) and agō (“to drive, lead”).[7][1][4] Bénaben and the DHLF explain the sense as “driving from one side to the other”, hence “to hesitate”;[8][9][10] Gómez de Silva glosses the adjective literally as “wandering”.[8][9][10] De Vaan lists the compound verb, glossed “to dispute”, and the adjective among the derivatives of the simple verb, which goes back to Proto-Indo-European *h₂eǵ- (“to drive, lead”).[11]

The same Latin word was borrowed as Portuguese ambíguo, Catalan ambigu, French ambigu and Italian ambiguo.[12][13][1] The French adjective, used as a noun for a cold collation served all at once, was taken back into Spanish as ambigú.[4][5]

Earliest recorded meaning

The TDHLE's first quotation, from a document of 1539 printed in the Colección de documentos inéditos of America and Oceania, uses the word of people who do not know where to turn: the natives andan ambiguos, no sabiendo a quién ocurrir “go about undecided, not knowing to whom to turn” when they need justice.[2] The DCECH and the BDELC date it from Las Casas, about 1560; the noun ambigüedad is older, in Palencia's vocabulary of 1490.[4][5]

Semantic evolution

In the 16th and 17th centuries the adjective meant “undecided, irresolute” of people and “doubtful in outcome” of events, and also “equivocal, open to two readings” of answers and words, as of the oracles in the Crotalón (c. 1553).[2] The Diccionario de Autoridades (1726) defined it as a doubtful and confused thing that can be applied in different senses, and added the grammatical género ambiguo; the 1770 edition explained it with el puente and la puente, el mar and la mar.[14][15] In 1884 the Academy gave the definition still used, “that can be understood in several ways and so cause doubt”, said especially of language.[16]

From the end of the 19th century the word was also used of sexual ambiguity: Rubén Darío wrote of himself con Verlaine ambiguo in 1905.[2] Moliner records the colloquial sense “somewhat effeminate”.[17] Gaspar y Roig (1853–1855) give technical uses in botany and mineralogy.[18]
