There is a class of verbs in French which require that their complement verb be in the indicative. However, if the matrix clause contains a negative or an interrogative, the complement verb is usually in the subjunctive, but sometimes in the indicative. Examples are the verbs "penser" and "croire" in sentences such as: 1) Elle ne croit pas que Jean est intelligent. and 2) Elle ne croit pas que Jean soit intelligent. Traditional grammar books usually offer confusing explanations of these facts, based on loose, impressionistic, quasi-semantic pronouncements, often contradictory in detail. It is the hypothesis of this paper that an explicit rule can be formulated to account for this class of verbs and that the facts of French are analogous to those of English which are accounted for by the rule of Negative Transportation. The problems inherent in such a position are considered here, and the conditions of the application of the Negative Transportation rule are examined. (Author/PMP)
