Derivational morphology is a process by which a grammatical expression is turned into a noun phrase. For example, in the sentence "Combine the two chemicals," combine acts as a verb. This can be turned into a noun via the addition of the suffix -ation, as in "The experiment involved the combination of the two chemicals." There are many suffixes ...

Phrase structure rules break sentences down into their constituent parts. These constituents are often represented as tree structures (dendrograms). The tree for Chomsky's sentence can be rendered as follows: A constituent is any word or combination of words that is dominated by a single node. Thus each individual word is a constituent.
Almost every noun phrase bears at least one thematic relation (the exception are expletives). Thematic relations on a noun are identical in sentences that are paraphrases of one another. Theta roles are syntactic structures reflecting positions in the argument structure of the verb they are associated with. A noun may only bear one theta role.

[1] Play is commonly associated with children and juvenile-level activities, but may be engaged in at any life stage, and among other higher-functioning animals as well, most notably mammals and birds.
A further modification is the lexicalized PCFG, which assigns a head to each constituent and encodes rule for each lexeme in that head slot. Thus, where a PCFG may have a rule "NP → DT NN" (a noun phrase is a determiner and a noun) while a lexicalized PCFG will specifically have rules like "NP(dog) → DT NN(dog)" or "NP(person)" etc.
