What kind of phrases are these?

"When love waned"
"When waves of greed surged across the country"
"When the homeless cried out bitterly in the slums"


What kind of phrases are these? I know they're not prepositional nor gerund phrases.

 

Also, are the following noun phrases?

"From commonplace interactions of people to the great events that shape the course of human history..."

Are "from the commonplace interactions of people" and "the great events that shape the course of human history" both noun phrases? If they are, that's what makes it parallel, right?

 

"When ....", is an adverb clause.

Noun clauses. One way to tell is to change the clauses to nouns and see if it works: From A to Z ...

 

Ginger is correct

The bolded are noun phrases (or noun clauses). In your question, you included the preposition from in the first noun clause, but the from is not part of the noun clause, though the noun clause is part of the prepositional clause that does include the from.

 

Thank you, guys, for your replies. I've gotten better responses from members of this site than from members of another site.

I'm curious, though, as to what you mean by "From A to Z."

 

I traded "commonplace interactions of people" with 'A' and "the great events that shape the course of human history" with 'Z' leaving "From" and "to" in place.

From one to another
From X to Y
From noun to noun

It gives one evidence the phrases were indeed nouns in that sentence.
