wiktionary
Borrowed from American Spanish avocado, altered—by folk-etymological association with abogado(“lawyer”)—from the earlier aguacate, which comes from Classical Nahuatl āhuacatl(“avocado”). (Can this(+) etymology be sourced?) Doublet of abacate.
The first mention can be found in the 1696 catalogue of Jamaican plants. [1]
etymonline
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.
