Pronunciation
Forms
formigueiro m (plural formigueiros)[1] A letter of 1821 spells it furmigueiro.[2]
Etymology
It is formed from Portuguese formiga (“ant”) + -eiro.[3][4][5][1] Wiktionary notes that it may correspond to a Vulgar Latin *formīcārium.[1] The same derivative is found across Romance: Spanish hormiguero, Catalan formiguer, Italian formicaio and Romanian furnicar.[6][1]
The base noun comes from Latin formīca (“ant”).[6][7] De Vaan reconstructs an earlier *mormīkā-, and Wiktionary explains the initial /f/ as a dissimilation of /m…m/ and links the word with Proto-Indo-European *morwi- (“ant”), a term whose forms vary widely across the Indo-European languages.[7][1]
Earliest recorded meaning
Houaiss dates the word to 1529, in the sense “home of ants”.[3] Cardoso's dictionary of 1569 renders it with Latin formicarium.[8]
Semantic evolution
Bluteau (1712–1728) already has the figurative uses: a swarm of worms in a neglected wound, and a crowd of people, parecia hum formigueiro “it looked like an anthill”.[9] Morais (1813) records an adjective, ladrão formigueiro “a thief who steals small things”, which the DLP marks as popular and dated.[10][4] Vieira (1871–1874) adds the sense of an ardent restlessness, and Figueiredo (1899) a prickling of the skin as if ants were crawling over it and a disease of horses' hooves.[11][12]
In the Azores formigueiro is the south-east wind, which blows from the Formigas rocks north of the island of Santa Maria.[3][13][4] In Brazil the word also names a tree of Mato Grosso, Triplaris, otherwise called formigueira, and in the north-east a pins-and-needles feeling in the legs.[5][14]
