An examination of the discourse-structuring functions that formulae perform in two genres which exist in written format as texts, but maintain close links to oral forms, namely Old English (OE) verse, specifically the epic poem Beowulf, and weblogs. We identify five important functions of formulae found in common across OE verse and blogs, classifying these functions as discourse-structuring functions, filler functions, epithetic functions, gnomic functions, and tonic functions. In addition, a sixth type of formulaic function necessarily tied to the written medium, the acronymic function, is identified in both genres.
