"chemical released by an animal that causes a specific response when detected by another animal of the same species," but the exact definition is much debated; 1959, coined (by Karlson & Lüscher) from Greek pherein "to carry" (from PIE root *bher- (1) "to carry," also "to bear children") + ending as in hormone.
