A Non-test for Ambiguity
Arnold M. Zwicky, Jerrold M. Sadock · Canadian Journal of Philosophy · 1987
In a recent article in this journal, Roberts (1984) suggests a semantic method for distinguishing ambiguity and generality, a method which is intended to avoid the problems that others such as Zwicky and Sadock (1975), Hintikka (1973), and McCawley (1980) have found in making such a decision. Roberts claims that his test derives its validity from the observation that an ambiguous expression has a disjunction of meanings, whereas a general expression has but one meaning (which might be disjunctive).
