Hmmm?
Well, Websters II University dictonary defines “Repertory” as
“A theater in which a resident company presents plays from a specified repertoire, usu. in alternation.”
So, it’s a theater where you have one group of players, vs some place like the National in DC (or most theaters on Broadway) where actors play roles, then when the play’s run is over, a different group of actors put on a different play.
(Generally), a repertory theatre uses the same cast to play a set list of plays each season. This differs from a theatre in which each play is staged separately with each cast being recruited independently for each play or each play being imported, intact, from various travelling shows.
The list of plays is the repertory or repertoire on which the theatre relies for presentations.
Repertoir - The stock of songs, plays, operas, or readings a player or company of players is prepared to perform.
If Winchester rifle decides to treat it’s employees to Annie Get Your Gun, they call the agent and find out who has that in their repetoir, so they can be booked for one night.
