Is there any difference between 一緒に and と一緒に?




と is used with 一緒に when you want to explicitly name with whom the action is
being performed. You usually need a noun/pronoun with と to make it clear who
or what that is.

> 一緒に行こう！ Let's go together.  
>  友達 **と** 一緒に行った。 I went with my friend.

By the way, と一緒に is not a set phrase as you appear to think it is. It's just a
standard use of the particle と.
