mól

noun. slave, thrall

móla

adjective. enslaved

mólanoldorin

proper name. Language of enslaved Noldor

A name for the dialect of the Noldor enslaved by Morgoth in linguistic notes from the 1930s, replacing a rejected form Múlanoldorin (LR/177). Both forms appeared in The Etymologies (Ety/MŌ), where it seems to be a compound of móla “enslaved” and Noldorin.
