The grammar of the english verb phrase part 74

Chapters 3 to 7 deal with the meaning and use of the four 'absolute' tenses — roughly speaking, those tenses which relate the time of a situation directly to speech time.

The head clause establishes an indefinite pseudo-pre-present subdomain which is expanded as if it were a past domain. a Tom s father has known for some time that Jane and Tom are married. The head clause establishes a continuative pre-present domain the that-clause establishes a present domain of its own. b Once Jane and Tom are married and have gone off to Angola we ll let Tom s father know that they are married.
