avocado (n.)

edible, oily fruit of a tree common in the American tropics, 1763, from Spanish avocado, altered (by folk etymology influence of earlier Spanish avocado "lawyer," from same Latin source as advocate (n.)) from earlier aguacate, from Nahuatl (Aztecan) ahuakatl "avocado" (with a secondary meaning "testicle" probably based on resemblance), from proto-Nahuan *pawa "avocado." As a color-name, first attested 1945. The English corruption alligator (pear) is 1763, from Mexican Spanish alvacata, alligato.
