Hypotheses are one of the most important tools in scientific research. Yet they have received little attention linguistically and rhetorically. There has been a great deal of work on hedges - markers of tentativeness - which form an integral part of hypotheses. But that work has not focused on hypotheses per se, which have additional properties and functions. This paper examines the role of hypotheses in several introductory science texts, including the various elements normally associated with hypotheses, such as: assumptions, generalization and prediction, observation and experiment, induction and probability. It discusses the major types of hypotheses: theoretical, statistical, and heuristic. We will then analyze the various patterns that hypotheses take, including some of the more subtle epistemic elements (words expressing degrees of certainty) that tend to mark them. Following that we will look at several lexical items that playa role in hypothesis making, specifically: synonyms, collocations, and hedges. And finally, we will offer some considerations for the teaching of hypotheses.
