the only deer where both sexes grow antlers, then drop them like seasonal flexes
means A large deer of cold northern regions, with branching antlers in both sexes, often herded or kept semi-domesticated and known in North America as the caribou.
from From Old Norse 'hreinn,' meaning the animal itself, plus 'dyr,' meaning beast — so 'reindeer' literally doubles up as 'reindeer-deer,' since 'hreinn' was already the whole word. English borrowed it from Norse-speaking neighbors and tacked on its own 'deer' for good measure. 'Dyr' is a cousin of English 'deer,' which once meant any wild animal before it narrowed to the antlered kind.
