Word Origin for antenna
1640s, "feeler or horn of an insect," from Latin antenna "sail yard," the long yard that sticks up on some sails, of unknown origin, perhaps from PIE root *temp- "to stretch, extend." In the etymological sense, it is a loan-translation of Aristotle's Greek keraiai "horns" (of insects). Modern use in radio, etc., for "aerial wire" is from 1902. Adjectival forms are antennal (1834), antennary (1836), antennular (1858).
