Capable of deviating or turning aside from a standard course, rule, or pattern.
From deviate + -able suffix. Deviate comes from Latin deviare, combining de- (away) + via (way/road), literally meaning to leave the road.
The word 'deviable' is theoretically correct but practically invisible in modern English—most writers would just say 'able to deviate.' But it's perfect for describing systems that CAN diverge, emphasizing the potential rather than the act itself.
