Essentially, the tree model works something like this example, in which S is a sentence, D is a determiner, N a noun, V a verb, NP a noun phrase and VP a verb phrase:
S
/ \
NP VP
/ \ / \
D N V NP
/ \
D N
The resulting sentence could be The dog ate the bone. Such a tree diagram is called a phrase marker. They can be represented more conveniently in a text form, (though the result is less easy to read): in this format the above sentence would be rendered as:
((The dog) (ate (the bone)))or
((D N) (V (D N)))or
1.1. The 1. dog 2. ate 3.1. the 3. bone.
