Apron (n) – The area downstage of the proscenium arch.
Auditorium (n) – Where the audience sits. Also referred to as ‘the house’.
Bar (n)– A long piece of steel (preferably cylindrical – but sometimes not!) to hang things on.
Boom (n)– An upright, or vertical, bar usually for lighting but sometimes to support scenery.
Borders (n) – Rectangular pieces of black cloth (usually velvet or wool) that create a ‘border’ across the top of the stage picture. They are there to mask the other items in the grid.

Cyclorama (or cyc) (n) – a large screen (usually white) that is used to put coloured lights on to change its colour. Sometimes this is built-in, sometimes it is curved and sometimes it is hanging on a fly line. Most theatres will ‘grid the cyc’ so that it stays hanging and doesn’t get creases or dirty while not used on a show.
Deads (n) – The point at which the fly line has to stop to be at a certain point. Often marked with coloured tape on a hemp system.
Downstage (n) – The area closest to the auditorium. This term comes from when stages were usually raked. To go ‘down the rake’ was to go towards the audience.
Downstage (v) – To go towards the auditorium.
Drift (adj) – The distance between the bar at its highest point and its lowest point.
Fly floor (n) – The place where the fly lines are operated, usually higher than stage level. It can either be on prompt-side or opposite-prompt.

Fly line (n) – The line of a bar that can fly in and out.
Front of House (n) – The area that the public sees. This includes the foyer, toilets, bar and auditorium.
Grid (n) – A steel ‘grid’ or series of channels that can be used to rig onto. They vary depending on whether you are in a proscenium arch theatre, or in a studio type setting.
Grid (v) – To fly something out so high that it can’t be seen by the audience.
In (adj)– Towards the ground, or down.

When the Stage Manager needs to be located on the other side(or stage right) because of tight wing space or the set, that side becomes ‘Bastard Prompt’.

Raked (a) – To be sloped.
