A:

This probably belongs on english.SE, but in any case, the word you're looking for is sophont.
It's a real wordword accepted by at least a handful of dictionaries, credited originally to Poul Anderson, that has been used in a number of SF works and means exactly what you want. No need to reinvent the wheel here.
