Greek meta- is equivalent to the Latin words post- or ad-

Is this the right board to post this? I find this interesting. Usually nowadays 'meta' is used as: 'In epistemology, the prefix meta- is used to mean about (its own category)'. Originally it was: Meta (from the Greek preposition and prefix meta- (μετά-) meaning "after", or "beyond"), and that meant Post-Transhumanism & Meta-Transhumanism would have meant the same thing.
