What's the etymology of "harelip"? [closed]
I know it's no longer used much, having been replaced by the more clinical "cleft lip".
The spelling makes me suspect it's named for the animal, as rabbits have a similar feature on their faces, but couldn't find any decent evidence thereof.
Solution 1:
According to the OED, it is:
Fissure of the upper lip, caused by the arrest of development in the upper lip or jaw; so called from the resemblance to the cleft lip of a hare.
