ABSTRACT
A deletional transformation in transformational grammar which deletes the subject noun phrase (NP) of an embedded sentence ( embedding) if it is coreferential with an NP of the matrix sentence. Equi-NP deletion is used in the generation of infinitive constructions, e.g. Philip asked Caroline to drive, which can be generated from the two sentences Philip asked Caroline and Caroline drives, The second mention of Caroline is deleted and the form drive is changed to the infinitive. ( also control)
Philip asked Caroline to drive.
