meant to come up with a new word or subject, or term a word or subject that had not previously been named

Putney, welcome to the board. Does your name mean you are from Putney (London UK) or is it like Chelsea Clinton? And is Swope the past of swipe? Don't answer if you think it may incriminate you.
To answer your question:
neologism = noun meaning either a new word, or the coining of a new word. I doubt if the verb is "neologise/-ize" though . I would use "to coin a neologism" or similar. Is there a better verb for this?

Be warned however, Mirriam-Webster gives the secondary meaning of:
"a meaningless word coined by a psychotic"
