"of the same parents or grandparents," c.1300, from Old French germain "closely related" (12c.), from Latin germanus "full, own (of brothers and sisters); one's own brother; genuine, real," related to germen (genitive germinis) "sprout, bud," dissimilated from PIE *gen(e)-men-, from root *gene- "to give birth, beget" (see genus).

"Teuton, member of the Germanic tribes," 1520s (plural Germayns attested from late 14c.), from Latin Germanus, first attested in writings of Julius Caesar, who used Germani to designate a group of tribes in northeastern Gaul, origin unknown, probably the name of an individual tribe. It is perhaps of Gaulish (Celtic) origin, perhaps originally meaning "noisy" (cf. Old Irish garim "to shout") or "neighbor" (cf. Old Irish gair "neighbor"). The earlier English word was Almain (early 14c.) or Dutch.
