deadlier
Increasingly likely fatal
Deadlier is the comparative form of deadly—more likely to cause death or more lethal: The newer strain proved deadlier than the original.
It applies to weapons, diseases, predators, or anything capable of killing: a deadlier poison, a deadlier aim.
Figuratively, deadlier describes greater effectiveness at destruction: Her wit was deadlier than his.
