tamin

noun. forge

A word appearing as ᴱQ. tamin or tamilla “forge” in the Qenya Lexicon and Poetic and Mythological Words of Eldarissa of the 1910s under the early root ᴱ√TAMA “beat; smelt, forge” (QL/88; PME/88).

Neo-Quenya: The root √TAM was glossed “construct” in Tolkien’s later writings, and its derivative tamo was often used for “[metal] smith”, so I think ᴺQ. tamin “forge” can be retained as a derivative based on the later meaning of the root.

tam-

verb. to tap

A verb in The Etymologies of the 1930s appearing as tamin “I tap” under the root ᴹ√TAM “knock” (Ety/TAM). See the entry ᴹQ. ton- for other similar “tap, knock” verbs.
