What are pragmateia and pragmata, and how do they relate?

I am reading François Laruelle’s Biography of Ordinary Man and, in the final section he deals with pragmatics and seems to be drawing largely from Wittgenstein (with regards to the latter’s conception of games and “use”) with whom I’m entirely unfamiliar. Laruelle makes the claim that in standard philosophical accounts, pragmateia and pragmata are necessarily linked. I’ve tried going through wiktionary and some other resources but I’m still at a loss for: what these two terms refer to individually, and how they relate.
