Is as soon a conjunction?

"As soon" is not a conjunction. It's a phrase, often used as an adverb to indicate the immediacy of something happening. Here's a breakdown:

* "As" is a conjunction, used to introduce a subordinate clause. It can indicate comparison, time, or cause.

* "Soon" is an adverb, indicating time.

Together, "as soon" acts as an adverbial phrase, modifying verbs and indicating that something will happen very quickly after something else.

Examples:

* As soon as the bell rang, the students rushed out. (The students rushed out immediately after the bell rang.)

* As soon as you finish your work, we can go. (We will go immediately after you finish your work.)

While "as soon" might feel similar to conjunctions like "when," it's important to understand that it's a phrase working together as an adverb, not a conjunction.
