Backlash is the slop or play in a mechanism caused by gaps between the parts. Generally, this is defined as the amount of clearance in the device after motion is applied and before the mechanism activates. An example would be turning a steering wheel in a car, and feeling the loose motion before the steering engages. Backlash is usually not desired in most industrial applications, although occasionally some amount of backlash is necessary.
