Abstract
To determine whether there are different technical styles, syntactic structures at three audience levels in the published writing of three disciplines were analyzed. Our analysis discloses that different disciplines rely primarily on different types of subordinate clauses, sentence openers, and sentence types. It also discloses that paragraph length varies with audience level, as do the number of subject sentence openers and the kinds of verb constructions. Next, we compare our findings with standard textbook treatments of style and advocate a more flexible approach to the teaching of technical style, one that accounts for variations in subject matter and audience.
