Quiz: Remember the definition of mal de mer?
animal doctor, 1640s, from Latin veterinarius "of or having to do with beasts of burden," also "cattle doctor," from veterinum "beast of burden," perhaps from vetus (genitive veteris) "old" (see veteran), possibly from the notion of "experienced," or of "one year old" (hence strong enough to draw burdens). Another theory connects it to Latin vehere "to draw," on notion of "used as a draft animal." Replaced native dog-leech (1520s).
