Forms

lado m (plural lados)[1] Houaiss records a 15th-century spelling llado.[2]

Etymology

It is inherited from Latin latus (“side, flank”), written Old Galician-Portuguese lado in the oldest texts.[2][3][1][4] The Latin noun was neuter, with the same form in the nominative and accusative;[5][6] Nascentes explains the Portuguese word from a form ⟨latu⟩, the noun being declined as if it belonged to the second declension.[5][6] Aurélio instead derives it from the neuter form through an intermediate ⟨lados⟩, and the DCECH shows such a singular in early Spanish documents, in the phrase ⟨al lados de⟩ “beside”.[7][8]

The same Latin word is Spanish lado, Italian lato, Old Occitan latz, Old French lez and Romanian latură.[9][1] De Vaan finds no good etymology for the Latin noun, an old “s”-stem: a link with sliss (“side”) and its Welsh cognate is attractive in meaning, but the preform it requires would have given a different Latin word, and he also considers a derivation from lateō (“to be hidden”).[10]

Earliest recorded meaning

The first records are of 1280.[2][11] A document of that year quoted in Viterbo's Elucidário has lados for loins of pork, in a list of what was owed, and the Cantigas de Santa Maria have viu de lado / cabo da porta estar / a virgen “he saw the Virgin standing at the side by the door” and de cada lado “on each side”.[12][11][2]

Semantic evolution

The cantigas already use the word for one's party: seer do seu lado “to be on someone's side”.[11][13] Bluteau (1712–1728) records the side of a ship and the flanks of an army, and Morais (1813) adds a figurative use for the people who keep someone company, while marking the sense “loin of pork” as obsolete.[14][15] Modern dictionaries add the geometrical senses, “each line that bounds a figure” and “each face of a solid”, the senses “direction” and “aspect” and the side of a family: do lado materno.[2][16] Derivatives are early: ladear and ladeira “slope” are recorded in the 15th century.[3]

Usage notes

Common phrases are ao lado “beside”, lado a lado “side by side”, de lado a lado “from end to end” and pôr de lado “to set aside, to give up”.[20][16]

The old language also had an adjective lado, feminine lada, “wide, broad”, from Latin lātus (“broad”): the Crónica Troiana speaks of eyebrows ladas et grossas, and Morais (1813) still quotes barcas grandes, ladas from Barros.[11][15][1]
