Will before we went out be a phrase?

"Before we went out" is not a complete phrase on its own. It's a phrase fragment.

Here's why:

* It lacks a subject: Who is doing the action of "going out"?

* It lacks a verb: There's no action happening in the phrase.

To make it a complete phrase, you need to add a subject and a verb. For example:

* Before we went out, we had dinner.

* Before we went out, it started raining.
