Examples of noun modifiers include
1. Adjectives
2. Preposition
3. Past Participle
4. Present participle without commas
After the table, there are these 2 more examples
The cat, which lives next door, is very noisy
The cat that lives next door is very noisy
So I guess that "which lives next door" and "that lives next door" are examples of noun modifiers too right? So, in the table above, I can add "subordinates introduced by which/that", right?
I looked in the internet too, for example here the term "noun modifier" is used in a completely different way. It means a noun that follows another noun (e.g. "a school teacher", "an office worker", "some grammar practice exercises")
Thanks
