Motley is an adjective that means ‘of diverse composition.’ 

Our word of the day’s precise origin is unknown, but we know it’s from the Late Middle English period and can be thought of as a synonym of assorted or varied. Here’s an example of motley in use:

They sent a pretty motley group of employees to the conference. The group included guys with varying levels of competence, dependability and ability. They might have been better off making sure everyone at the conference was equally skilled.
