Pronunciation

Forms

tronco m (plural troncos)[1]

Etymology

It is inherited from Latin truncus (“trunk of a tree or body”).[2][3][4][1]

The same Latin word is Galician tronco, Spanish tronco, Catalan tronc, French tronc and Italian tronco.[5][6][1]

De Vaan takes the Latin noun from an older adjective of the same form meaning “maimed, trimmed”, a tree or body robbed of its branches or head, and rejects the proposed links with Germanic and Lithuanian verbs for pushing.[7] Wiktionary calls it of unknown origin, perhaps from *twerḱ- (“to cut”).[1]

Earliest recorded meaning

A Latin charter of 1060 already has iacia in tronco et in katena “he lay in the stocks and in chains”, with the Romance spelling.[8] Houaiss and Cunha date the Portuguese word to the 13th century.[2][3] The Horto do Esposo, copied 1390–1437, has the first record in the dated prose corpus.[9]

Semantic evolution

Besides the trunk of a tree and of the body, the word named from the start the wooden stocks in which prisoners were held, which led to the sense “prison”: Pereira (1697) translates it carcer.[8][10] Folqman (1755) and Morais (1789) add tronco de geração, the ancestor in whom a family began, and the figurative sense “blockhead”.[11][12]

In colonial Brazil the tronco was the post or stocks to which slaves were tied to be flogged.[2][13][1] Other senses are a frame for holding cattle to be branded, a ship's mast, a frustum in geometry, and in linguistics the top level of a language family; in Ceará it means drunkenness.[2][14][1] The prison sense passed into Dutch and Afrikaans as tronk.[1]
