A neologism for “to feed” coin by Damien Bador as a straightforward derivative of the attested primitive verb ✶matyā- of the same meaning (PE22/135). I would distinguish it from ᴺQ. nesta- “to graze, pasture, (give to) feed” used for feeding farm animals, whereas matya- can be used for feeding anyone.
Quenya
-matya
suffix. -eating
matya-
verb. to feed
An adjective suffix for “eating” used only in compounds based on an archaic active participle suffix -ya (PE17/68).
Conceptual Development: A similar suffix ᴱQ. -matwa appeared in various words in the Qenya Lexicon of the 1910s (QL/59-61).
