For example, in "There are two sequences meshed together":
-"two sequences" is a phrase functioning as an adjective and therefore an adjectival.
-"meshed together" is a phrase modifying "two sequences" which is a noun phrase.

**So what happens when a phrase modifies a noun phrase or noun that is an adjectival?** Is it considered an adverbial or adjectival?
My wavering notion is that when using words like "adjectival" or "adverbial", I am doing an analysis beyond phrase analysis.

Phrase analysis = figuring out the phrase types in a sentence based on composition.
