a. Lexical entries for the words in the Japanese phrase in the example are:
kono: demonstrative pronoun "this"
kodomo: noun "child"
to: preposition "with"
b. A phrase structure rule for PPs in Japanese could be:
PP → P NP
Where PP represents a prepositional phrase, P represents a preposition, and NP represents a noun phrase.
c. Here is a phrase structure tree for the Japanese phrase "sono hito to" ("with that person"):
PP
___|___
| |
P NP
| |
"with" "that person"
In this tree, "sono hito" ("that person") is the NP, and "to" is the preposition that forms the PP. The PP is attached to a higher structure in the tree, such as a sentence or a larger phrase.
