"the Big Dipper, the seven prominent stars of the Great Bear;" Middle English septentrioun (1530s in reference to the star pattern; late 14c. as "the North," and septentrional "northern," in reference to the sky, is attested from late 14c.), from Latin septentriones, septemtriones (plural) "the Great Bear, the seven stars of the Big Dipper;" also figuratively "the northern regions, the North;" literally "seven plow oxen," from septem "seven" (see seven) + trio (genitive triones) "plow ox," from stem of terere (past participle tritus) "to rub" (from PIE root *tere- (1) "to rub, turn").

"association between organisms in which one is carried on the body of another but is not a parasite," 1914, from French phorésie (1896), from Greek phorēsis "being carried," from pherein "to carry," from PIE root *bher- (1) "to carry," also "to bear children."
16c., from French furtif (16c.), from Latin furtivus "stolen," hence also "hidden, secret," from furtum "theft, robbery; a stolen thing," from fur (genitive furis) "a thief, extortioner," also a general term of abuse, "rascal, rogue," probably from PIE *bhor-, from root *bher- (1) "to carry; to bear children."
