Capable of being ensued or followed; that which can be pursued or comes after.
From 'ensue' (to follow after) plus '-able' (capable of). The word follows standard English adjective-formation patterns, describing something that has the quality of being able to follow or result.
This word is a grammatical ghost—it appears almost nowhere in practice because 'ensue' doesn't typically need an adjective form, showing how English speakers abandoned word-formations that didn't fill a real communicative need.
