Presents embedded under pasts
According to traditional grammar, this is a sentence where sequence of tense has failed to apply (i.e., concord has been broken): standard sequence of tense rules would dictate use of a past tense when embedding an event contemporaneous to the embedding verb under a past tense verb, giving the sentence John said that Mary was pregnant . For some verbs breaking concord is impossible (*Mary said that John builds a house) or can only have a present-as-future interpretation (John said that the last spaceship to Mars leaves tomorrow), but with stative verbs, as Enç (1987) and others have observed, this failure of sequence of tense to apply is associated with a rather special meaning, which we will try to elucidate below. For the moment, let us merely observe that the use of present tense seems to cause such sentences to end up saying something about a larger interval including both the time of utterance and the time of the event described in the main clause. For this reason Enç calls them “double access sentences”, but that seems a rather dubious name as the interpretation seems to rely on evaluation at a large interval, not just at two points.
