Definitions

Etymology: The ending "-er" marks this as an agent noun, a word for someone or something that does a particular action. The verb it was built from, however, is uncertain to me. The sense given, a covering or protective garment or a person who shields another, fits the agent pattern, but that connection is inferred from the form rather than from attested history. A dictionary of historical English or a regional dialect dictionary would be the place to check whether the word was recorded and in what sense.

Synonyms: sleeper, slayer, player, heater, dealer
