Forms

isca f (plural iscas)[1] The 14th century wrote ysca.[2][3][4]

Etymology

It is inherited from Latin ēsca (“food; bait”), written Old Galician-Portuguese ysca in the 14th century.[2][3][5][1] Its initial ⟨i⟩ is a difficulty, which the sources explain in different ways.[2][5][3] Nascentes supposes a Vulgar Latin form with a short ⟨e⟩, perhaps after edō (“to eat”).[5] Houaiss reports Machado's remark that the ⟨i⟩ might point to a back-formation from iscar.[2] Cunha starts from an inchoative verb of the same root.[3]

The same Latin word is Galician isca and Galician esca, Spanish yesca, Catalan esca, Italian esca, French esche and Romanian iască.[1][6][7][8] In Late Latin the word took the sense “what feeds the fire”, which gave the Spanish word its sense “tinder”.[8][9][10]

De Vaan derives the Latin noun from the root of the verb with a suffix ⟨-sk-⟩, and the root goes back to Proto-Indo-European *h₁ed- (“to eat”).[11][1]

Earliest recorded meaning

The first record, in a 14th-century Galician Estoria quoted by Lorenzo, has the tinder sense: with the bow a man found seu esqueyro et sua ysca et seu pedernal “his tinder pouch, his tinder and his flint”.[4][2]

Semantic evolution

Nascentes thinks the word was first taken as the food of the fire, as isqueiro shows, and then as the bait put on a hook; the strips of liver called iscas would be named by comparison with bait.[5] The esqueyro of the 14th century was the pouch for tinder, flint and money; the sense “lighter” is modern.[12] Morais (1813) has the fish or meat put on the hook, the tinder, and the figurative lure (as delicias são isca dos vicios, after Barros).[13] Vieira (1871) records pegar a toda a isca, said of a greedy man who bites at any gain.[14]

Figueiredo (1899) adds the popular strip of liver fried in lard.[15] In Portugal iscas are thin slices of seasoned fried liver, and in Porto strips of salt cod fried in batter; in Brazil the word also means sugar-cane spirit, and in Minas Gerais an earthworm.[2][16][1]

Usage notes

Morder a isca “to take the bait” is to fall into a trap.[2][1]

Houaiss enters separately a Brazilian interjection isca!, used to set dogs on, as the imperative of a second verb iscar “to set on (dogs)” of doubtful origin.[2][5][19] Nascentes reports that Amadeu Amaral took that iscar for a shortened form of buscar.[2][5][19]
