hare = заєць
rabbit = кролик

Is this a common word in Ukrainian? I don't think I would ever use hare in everyday English unless referring specifically to something like the story "The tortoise and the hare" or maybe in a biological discussion if I wanted to be really accurate. Otherwise, I would just use "rabbit" incorrectly even when referring to a hare.
