A verb appearing as ᴱQ. tyuku- “to chew” with variant tyukta- in the Qenya Lexicon of the 1910s derived from the early root ᴱ√TYUKU of the same meaning (QL/50).
Neo-Quenya: I’d retain this verb as ᴺQ. tyuc- “chew” for purposes of Neo-Quenya, derived from the Neo-Root ᴺ√TYUK.
The verb ᴱQ. mal- “to crush” and mala- “crush, squeeze” appeared in the Qenya Lexicon of the 1910s based on the early root ᴱ√MALA (QL/58, 63). Tolkien also had a distinct but related verb ᴱQ. mala- “hurt, pain” from a related root ᴱ√MBALA (QL/58, 63).
Neo-Quenya: In The Etymologies of the 1930s, Tolkien had a root ᴹ√MBAL which was the basis for the word ᴹQ. malle “street”, which in the 1910s was derived from ᴱ√MALA “crush”. On this foundation, I would retain ᴺQ. mal- “to crush, squeeze”. For purposes of Neo-Quenya, I would further assume that this verb can also mean “to hurt, pain (cause pain to)” as an extended meaning, usable metaphorically for both physical and emotional hurt; Helge Fauskanger used mal- for “hurt” in his NQNT (NQNT).
