Forms
outro (feminine outra, masculine plural outros, feminine plural outras)[1] Houaiss records the medieval spellings outros, outre and outri in the 13th century, houtro and octra in the 14th, and otra, outrro and ouutro in the 15th.[2]
Etymology
It is inherited from Latin alter (“the other of two; second”), written Old Galician-Portuguese outro in the oldest texts.[2][3][4][1] Houaiss and Aurélio derive it from the accusative form, and Nascentes notes that the word for “the other of two” took the place of the Latin general word alius (“other”).[2][5][4]
The same Latin word is Galician outro, Spanish otro, Catalan altre, French autre, Italian altro and Romanian alt.[6][1] Corominas observes that Spanish, and to a large degree Portuguese, differ from the other Romance languages in not combining the word with the indefinite article um.[7]
The Latin word goes back to *aliteros (“the other of two”).[1] De Vaan reconstructs *h₂el-tero- (“the other of two”), built on the same root as *h₂el-io- (“another”), the source of the Latin word for “other” and of ἄλλος (állos) and 𐌰𐌻𐌾𐌹𐍃 (aljis).[8]
Earliest recorded meaning
Houaiss dates the pronoun to the 13th century, from Cunha's slips of medieval Portuguese.[2] The lyric of that century already uses it as today: the Cancioneiro da Ajuda has outra molher “another woman”, and the Crónica Troiana has sen outro deteemento “without any other delay”.[9]
Semantic evolution
The cantigas already have the fixed phrases outro tal “another such” and outrossi or outro si “likewise”, the source of modern outrossim.[9][10] Cunha dates outrem “someone else” and outrossim to the 13th century and outrora “formerly” to the 16th.[3]
Morais (1789) defines the word as “not the same, not identical; different, changed”, and quotes a virtude não he outra coisa que huma mediania entre dois extremos “virtue is nothing other than a mean between two extremes”.[11] Houaiss and the original Caldas Aulete add the sense “better, superior”, as in a thing that is outra coisa “something else, much better”.[2][12] In philosophy and the social sciences o outro is the other, as opposed to the self.[13][14]
The Spanish otrora “formerly”, used in Latin America and recorded from 1913, is taken from Portuguese outrora.[15]
