Probably the single word with the most definitions in all of theatre. Trim can mean/refer to: 1. The height of a suspended (flown) scenic piece. 1a. The level or plumb of an object. 2. To cut away a portion of material: cloth, wood, metal, plastic. 2a. To speed up time: "We need to trim the Second Act, it's running too long." 3. The "frilly" stuff (lace, rick-rack, fringe, etc.) on a costume or drapery. 4. The distance between electrodes of a carbon-arc light source. 4a. A set of the carbons themselves. 5. Physically fit, slender. 6. To adorn, "Trim the Christmas tree." 7. To adjust, "Trim the sails on a boat," (from where most of our rigging terms come). 8. The calibration of an analog dimmer. 9. Attenuation, as in the "trim pots" on a sound board. Others I forgot?
