The thing is, though, that the starter Pokemon basically always have something in their name that relates to their type.
Bulbasaur, Charmander, Squirtle
Chikorita, Cyndaquil, Totodile
Treecko, Torchic, Mudkip
Turtwig, Chimchar, Piplup
Snivy, Tepig, Oshawott (like "ocean")
Chespin, Fennekin, Froakie
Rowlet, Litten, Popplio
The only two that don't have their type referenced in their names outright are Totodile and Froakie, and in the latter's case, Fro might be for froth, while for the former, crocodiles themselves are so associated with water that it's almost unnecessary.
The "Li" part is definitely for Lit and not Liger.
