HOW TO BE MORE OR LESS CERTAIN IN ENGLISH: SCALARITY IN EPISTEMIC MODALITY

"Epistemic modality" is a rather vague term generally used to denote the kinds of qualification a basic Statement like he 's right undergoes in expressions such äs / think he's right, he must be right, perhaps he 's right, and so on. As such, it repiesents a major area of language use of obvious communicative importance. In functional terms, this is concerned with expressions of, for example, "certainty and uncertainty", "degrees of probability" and "speculations about the past, present and future", all to be subsumed under "expressing and finding out intellectual attitudes" in Threshold Level terminology (van Ek, 1977: 45-7).
