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!
The verb ᴱQ. ter- appeared untranslated in a list of Qenya Verb Forms from the 1910s (PE14/28). Patrick Wynne and Christopher Gilson suggested it might be based on the early root ᴱ√teře “pierce” from this same period (PE14/28 note #4; PME/91).
Conceptual Development: The root √TER “pierce” appeared several times in Tolkien’s later writings (Ety/TER; PE17/33), so I would use ᴺQ. ter- “to pierce” for purposes of Neo-Quenya. For example, Helge Fauskanger had the active participle ᴺQ. térala “piercing” for his NQNT (NQNT). I would use the active participle form terila myself, but I think the basic verb ter- is perfectly viable.
