 Despite this linguistic model, phrases may be extralinguistic, including the very gestures, shadings, and libidinal energetics he had discussed in his earlier writings. Anything, then, can be a phrase in Lyotard’s understanding. For every phrase, there is a regimen within which it exists, the possible significations of that phrase, the referent of the phrase, the one from whom the phrase arrives, and the addressee, the one to whom the phrase is addressed. Within each phrase regimen, there is a certain play, since there may be ambiguities along each aspect above. Any reader of Twitter knows the problem: is this meant as irony? In the form of a question? Who is being addressed and why? Only with continual phrases, linked to the initial phrase, does the initial ambiguity become clearer, but of course, with these newer phrases, further ambiguities may take place, since they face the same problems as the initial phrase. Nevertheless there are rules followed within phrase regimens such that certain phrases are allowable while others are not. Lyotard writes:
