Well, as Bob Dylan wrote in Brownsville Girl ‘if there’s an original thought out there I could do with it right now’

I think the word foonis should be a description of a dog. I know it's an original thought because I made up the word and therefore the thought.

Most of the time just having a THOUGHT takes about all I can muster up.

Every thought must have had a first originator just as every mountain had a first climber, but like finding new peaks it probably gets harder with time.

Now it would be very rare, but it would not be uncommon to have a thought which was new to the person you are talking to, and perhaps that is good enough. Thinking about it maybe that is an original thought ?

This question has been asked and answerd before.
