The language of sportscasting is analyzed in terms of register variation. 1 First the register is "located" by successive approximations to a characterization of its occasions of use, then selected syntactic characteristics are identified: simplification (deletion of copula and sentence initial nominals), inversions, heavy modifiers, result expressions (for + noun, to + verb), routines (e.g., giving the "count"). Some of these are discussed in relation to possible communicative functions, but all are seen as register markers. Sports announcer talk (SAT) is described as a promising topic for comparative, historical, and acquisitional studies of register variation.
