One who or that which ensues; something that follows as a consequence.
From 'ensue' plus '-er', the agentive suffix creating nouns for persons or things performing an action. Though grammatically sound, the word saw limited use because 'consequence' better served the semantic need.
This word is a linguistic oddity—grammatically perfect but practically useless because English already had better nouns for the concept, showing how word-formation rules can create technically valid words that communities simply don't adopt.
