Hi. I'm trying to write a definitine clause grammar:



So far for the first bullet point, I have written (please read after //... for my problem):

Sentence --> pronoun, verb // do I enter the "noun-phrase or an adverb" here? And why? I'm confused because if I were to separate it on another line, there appears to be no parameters
Pronoun --> [he]
Pronoun --> [she]

verb --> [sees]
verb --> [smells]

noun_phrase --> determiner
pronoun --> [his]
pronoun --> [her]
noun --> [food]

My lecture slide shows:



So perhaps it should be:

Sentence --> pronoun, verb
Sentence --> noun_phrase
Sentence --> adverb

?

The solution in your second post is wrong because it says "a sentence must have noun_phrase and an adverb", but what we want is "or", not "and".

The solution in your third post is wrong because it says that a noun_phrases and adverbs can be sentences on their own - you no longer need a pronoun and a verb.

A correct solution would make sure that each sentence starts with a pronoun followed by a verb and that the third part is either a noun phrase or an adverb.

The most obvious way to express that (or at least the way that most closely matches the phrasing of the assignment) would be something like "sentence --> pronoun, verb, (noun_phrase OR adverb)", but there's no OR-operator in the list of notations you were given, so the only way you can express an choice is by using multiple rules.
