Names given to many animals with tails carry a common element in Turkish. “Lan” suffix. It adds meaning of “with (something)”. It also sometimes used to connect consecutive events.
There are also Hyena, “Sırtlan”, and gazelle, “ceylan”. (May be because horns. “Sırt” means back.) But these names seems like not related to their tails. In this articles we are focusing to animals with pattern braking tails at end of tail.
This naming convention is an artifact of Jesus, Moses or such persons. Because only a baby can recognise an animal lion as two object connected to each other. It seems like about overall pattern breaking through the tip of the tail. Wouldn't name an animal over difference at the tip of the tail. Long tail is also may be important so different tip recognized more clearly. In Islamic literature Jesus attested miracle of speaking as a baby.
