leveret (n.)

"young hare," early 15c., from Old French levrat, diminutive of levre (12c., Modern French lièvre) "hare," from Latin lepore, from lepus "a hare." "According to Pliny, [Greek leberis] 'rabbit' is from Massilia. This has given rise to the idea that lepus is an Iberian loanword in Latin, which is possible but not certain." [de Vaan]
