She is a talented theatremaker.

There are several theatrettes in the city.

I watched a movie at the theatrette.

Theatremaking is a collaborative process that involves writing, directing, designing, and performing.

She is a talented theatreperson.

The theatrepersons are rehearsing for the upcoming play.

The theatrepeople gathered backstage before the show.

The theatrelessness in this town is disappointing.

The atmosphere in the old opera house was theatrelike.
