Folks,
I'll suggest the following strawman as a start on a restricted English
grammar.
sentence
/ \
SNP|Q VP
/ \ / \
Det N|PN V NP|SNP
/ | \
Det M N|PN
where:
SNP = simple noun phrase
NP = noun phrase
Det = determiner [the|a|an|all|every]
N = noun
V = verb
VP = verb phrase
PN = proper noun
M = modifier
Q = query word [who|what|where]
