dispatchable positive

Morphology

dispatchable = dispatch (transparent) = dispatch + able

Derived from the computing sense of 'dispatch' (to assign/schedule), so learners familiar with that verb sense can infer the adjective.

Etymology

Dispatchable comes from the verb dispatch ('send to run') and the ending -able ('can be done'). In computing, to dispatch a process is to send it to be run, so a dispatchable task is one the system can schedule and start right away.
