Pronunciation

  • IPA: /ˈæl.ɪ.ɡeɪ.tɚ/; /ˈæl.ɪ.ɡeɪ.tə/ (UK)[1]

Etymology

It is an alteration of Spanish el lagarto (“the lizard”),[2][3][4][5][6] from el “the” (Latin ille “that”)[2][3][5] and lagarto “lizard”,[2][3] from Vulgar Latin *lacartus,[3][6] from Latin lacertus (“lizard”).[2][3][4][5] The Spanish phrase in full was el lagarto de Indias, “the lizard of the Indies”.[4][5]

Earliest recorded meaning

A large reptile of the Americas related to the crocodile, recorded in 1568 as lagarto.[7][2][4][5]

Semantic evolution

Early English forms were lagarto and aligarto;[4][5] the form allegater appears in Shakespeare in 1623.[2][4] The final -r is unetymological, as in tater and feller,[5] and the American Heritage Dictionary suggests the reshaping is a kind of taboo deformation, common in names of feared creatures.[2] The word was later applied to tools and machines with strong jaws, such as alligator clips.[2][7][6] In the swing era (1936) an alligator was a jazz fan who did not play,[7][5][6] and see you later, alligator is from a 1956 song title.[5]
