View source for CP-reduction

In generative syntax, a '''CP-reduction''' is a process which deletes [[CP]] (also known as S-bar deletion). 

===Examples===
In (i) ''expect'' assigns structural accusative ''Case'' to the subject (''Greg'') of its [[complement clause]] (''Greg to win''). This should not be possible if this clause were a full [[CP]], because ''expect'' could not govern the subject in that case ([[CP]] would be a [[barrier]]). If expects deletes CP, [[government]] is possible, as the remaining IP is not a [[barrier]] to [[government]].

(i)  ''Everybody expected [<sub>IP</sub> Greg to win ]''

CP-reduction has also been assumed to obtain in [[Raising to Subject]] constructions such as (ii):

(ii) ''John seems [<sub>IP</sub> t to have won ]''

In order for the trace of ''John'' to be [[properly governed]] by the matrix [[verb]], the embedded clause may not be a [[barrier]].

===Comment===
CP-reduction has been proposed to explain [[Exceptional Case Marking]] (ECM).
