Would time phrases be considered nouns?

That's a great question! It depends on how you're using the time phrase.

Here's why it can be tricky:

* Time phrases often function as adverbs: They tell us *when* something happens. Examples: "I'll see you tomorrow," "He arrived early this morning," "She'll finish the project in a few weeks." Adverbs modify verbs, adjectives, or other adverbs, and are not nouns.

* Time phrases can sometimes function as noun phrases: If they act as the subject or object of a sentence. Examples: "The next week will be busy," "I'm looking forward to the end of the year."

To figure out if a time phrase is a noun or not, ask yourself these questions:

* Can you replace it with a single noun? If so, it's likely a noun phrase. (Example: "The next week" can be replaced with "Next week" which is a noun)

* Does it function as the subject or object of the sentence? If so, it's a noun phrase.

In short: While time phrases are often adverbs, they can also be noun phrases in certain contexts. Pay attention to how they're used in the sentence to determine their grammatical function.
