I’m trying to understand the grammar of this sentence:
Avalanches are dangerous to mountain climbers.
What part of speech is the word mountain?
Answer
It is part of the noun phrase “mountain climbers”, which is itself the complement of the sentence. Specifically “mountain” is a noun modifier (also called an ‘attributive noun’ or a ‘noun adjunct’), modifying “climbers”. A noun modifier is a kind of noun.
