Gloss “nírë” by Eldamo Import

Is that force in the way of "compulsion" (like the noun of the verb "to force someone"),

or is it force in the way of "power" (the abstract property of mighty persons, like kings or emperors)?

It is "force" as in an exertion of will. Thus this "force" could apply to pushing over an object or carrying out an action. I'm unsure if it could apply to compulsion: tyar would seem more likely.

“Power” and “control” fall more under the root TUR and it’s derivatives:
