Beware, older languages below! The languages below were invented during Tolkien's earlier period and should be used with caution. Remember to never, ever mix words from different languages!
A (Noldorin-only?) root in The Etymologies of the 1930s whose derivatives have to do with “left” such as N. crom “left” and N. crumui “left-handed” (Ety/KURÚM). It seems this root had some “sinister” connotations, much like English/Latin uses of left, such as N. crumguru “wiley, sinister, guilty” (EtyAC/KUR). Left also had negative connotations in Tolkien’s earlier writings, such as G. gôg “clumsy; left (hand)” (GL/40). However, in the Ambidexters Sentence from 1969, Tolkien declared that Elves were ambidextrous and had no negative associations with “leftness”. I would recommend against using the root ᴹ√KURUM for the purposes of Neo-Eldarin, sticking to more neutral ᴹ√KHYAR instead.
