How do you use for as a conjunction?

You're right, "for" isn't traditionally considered a conjunction. It's primarily a preposition, used to introduce a phrase that tells us something about the noun or pronoun before it. For example:

* I went to the store for milk. ("For milk" tells us the purpose of going to the store.)

However, there are some cases where "for" can act like a conjunction, connecting two clauses and expressing purpose or reason. This is more common in formal or literary writing.

Here's how it works:

* "For" + clause 1, clause 2:

* Example: For the sun was setting, they hurried home. ("For the sun was setting" explains the reason they hurried home.)

In this example, "for" connects two clauses and introduces the reason for the action in the second clause.

Here are a few things to remember about "for" as a conjunction:

* It's less common than other conjunctions like "because," "since," or "as."

* It often creates a more formal tone.

* It can be replaced with other conjunctions to express the same meaning:

* For the sun was setting, they hurried home.

* Because the sun was setting, they hurried home.

So, while "for" primarily acts as a preposition, it can also function as a conjunction in specific cases to connect clauses and express purpose or reason.
