TITLE: How common is the use of the term "primitive" to mean "antiderivative"?
QUESTION [6 upvotes]: I don't know if this should actually be asked on the English stackexchange.  It seemed like I would find better answers here.  
I have all but finished an undergraduate degree in mathematics in the United States, but I have never once heard the term "primitive" to mean "antiderivative" until recently, when someone from Europe pointed it out to me.  According to him, it's a common term there.  So I was wondering if people could give me an idea of how common this term is, and where.  I know for sure that if someone says "primitive" to a math student in the US, that the student won't know what he is talking about. Does the reverse hold for "antiderivative" (or the also common "integral") elsewhere?

REPLY [4 votes]: Apostol's "Calculus" volume 1 uses "primitive" in that sense 41 times, whereas "antiderivitive" is only used 4 times. Two of those are in the main text, always as part of an "or antiderivative" after the term "primitive", and the other two are in the index.
