I am trying to understand how some noun phrases can sometimes be sentences such as:
A box filled to the brim. (NP)
A child covered in glue. (NP)
vs:
A child walked in the street. (S or NP)
A child asked to leave. (S or NP)
The first class is clearly ONLY a noun-phrase, yet the second appears to also be a S. I conjecture the NP reading as a deletion of the passive voice, which is causing the NP reading to take the form of the S in the 'walked' example:
A box [that was] filled to the brim.
A child [that was] covered in glue.
A child [that was] walked in the street.
A child [that was] asked to leave
For the VP cases, I see a different deletion:
*A box [that] filled to the brim.
*A child [that] covered in glue.
A child [that] walked in the street.
A child [that] asked to leave.
But I don't understand what it is about the verbs "fill" and "cover", vs "walked" and "asked" that disallows these first two forms, yet accepts the latter. Is my conjecture of the existence of these two types of deletion correct, and what is it that causes the (expanded) first two sentences to be incorrect?
Also of interest- are there any examples where the S reading is disallowed but the NP reading accepted?
