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!
A verb appearing in the Gnomish Lexicon of the 1910s as G. og- “am able, can” with variant ogra-, along with adjective forms G. ogra “able” and G. ogriol “possible” (GL/62). It had an associated noun form G. ogor “might, power; ability” so it was probably originally based on physical ability.
Neo-Sindarin: For purposes of Neo-Sindarin, I would use ᴺS. pol- for “to be (physically) able”; see that entry for discussion.
