Descriptive Text - Noun Phrase

Pre-modifier (affix that is placed in front of the noun)

Eg: She's the most beautiful person I ever met.

Main noun = person

Changed to a noun phrase because the phrase "the most beautiful" was in front of the noun playing.

Post-modifier (the affix that is placed behind the noun)

Eg: I really hate walking in the dark.

The main noun = walking

Walking becomes a noun with gerunds

Gerund = verb + ing

Changes to a noun phrase because the sentence "in the dark" is behind the main noun.
