Capable of being delayed; able to be postponed or put off without serious consequences.
From 'delay' + '-able' (capable of being). This adjective formation follows standard English morphology for describing what can be done to something.
The concept of 'delayable' versus 'non-delayable' tasks is crucial to productivity psychology—delayable tasks are exactly what people procrastinate on, while urgent ones get done immediately.
