Etymology

Origin of predictability

First recorded in 1850–55; predict(able) ( def. ) + -ability ( def. )

Explanation

Children with autism usually benefit from predictability in their schedules, where they can expect the same thing to happen routinely every day. Predictability has only one meaning, but it can be considered good or bad depending on the context. The predictability of sunrise and sunset is extremely helpful. If a mystery novel, however, suffers from predictability, there probably won't be very much "mystery" involved after all, and no one will want to read it.
