This project aims at better understanding how register knowledge relates to grammatical aspects of linguistic knowledge. It does so by specifically taking a comparative viewpoint and addressing aspects of the universal and language-specific nature of register variation. We will test our hypotheses by directly comparing three typologically different languages (Persian, German, Yucatec Maya) with widely different register distinctions through the parallel application of the same methods.

Languages greatly vary in register diversity. Some languages (Persian) show more salient differences between registers than others (German), in spite of both being used orally as well as in written form. Still other languages (Yucatec Maya) are mainly used for oral communication with only incipient written use.
