Forms

algo[1] Houaiss records the forms aligo (897, in a Latin charter), algo (1174), algu (13th century) and alguo (15th century).[2]

Etymology

It is inherited from Latin aliquod (“something”), the neuter of aliquis (“someone, something”), written Old Galician-Portuguese algo in the oldest texts.[2][3][4][1] The Latin pronoun is formed from ali- and the indefinite quis (“anyone”).[5]

The same Latin word is Spanish algo and Galician algo, and in Spanish, Portuguese and Galician it also came to mean “goods, wealth”.[6][7] From the phrase filho de algo, literally “son of something”, that is, of a man of property, came fidalgo “nobleman”.[8][4][6]

Earliest recorded meaning

A Latin charter of 897 already has the Romance form: et aliguno omine de isto que in testamento fesona aligo inde quesieri “and if any man wants anything from what is in this testament”.[4] A document of 1174 says that the addressees had done moyt algo “much good” for the settlement of Caína.[4] In the Crónica Troiana the word is both a pronoun “something” and a noun “riches, fortune”.[9]

Semantic evolution

In the medieval language the noun algo meant property and wealth, a favour or benefit, an improvement made to land, and income or gain; documents of 1178 and 1285 have fazer algo “to make improvements” on a holding.[10] In the cantigas fazer algo a alguém is to grant someone favours, and dar algo to make a gift.[9] The noun was common until the 16th century, but Morais in 1789 already marks it as antiquated.[9][11] Viterbo says it was also the title of men noble by birth and merit.[10]

As a pronoun and as an adverb “somewhat, rather” the word lives on.[2][12] Barbosa in 1611 already has algo mais “something more” and algo menos “somewhat less”.[13]
