The rule S-> NP VP reflects the fact that subjects and verbs are the only obligatory parts of a sentence. You can see in the sentence above that the verb vouloir agrees with the singular Noun monsieur, and this demonstrates that the main subject Noun is monsieur while the phrase qui porte des lunettes is simply part of the overall subject NP. At the same time, the NP un café is the object of the verb. Since some verbs do not require an object at all (as in Il arrive, Elle travaille), object NPs do not need to be represented in the rule S -> NP VP. It is for this reason that in tree diagrams, the NP directly below S is always conventionally understood as the ‘subject’, while the NP below VP is conventionally the ‘object’.
Our first rule of syntax reflects the fact that phrases combine to form sentences. A phrase is a sequence of words which belong together and function as a unit. All phrases orbit around one central element. For example, in Noun Phrases (NP), the noun represents the single most essential piece of information in the phrase. But NPs may also contain other information.
Naima hands her a couple English sentence trees that represent what she thinks the book is getting at, hopefully before Annisa can get too tripped up by the French.
" - hey, would it actually help more if we got Annisa book about English syntax and started with that, if we're gonna need to do English before French the whole time anyway?"
