I am a native English speaker (USA) and I just learned of the existence of "valuate". I have this terrible feeling that people have been saying it all around me my whole life and I have just assumed they were saying "evaluate".
My questions is whether or not "valuate" is in the common vernacular of most (American or British) native English speakers, or if it is a relatively obscure word. Should I be dumbfounded that I have never known this word before now?
