Discarder

Part of speech: noun

Definitions

1. A person who eliminates or gets rid of unwanted items or materials in a systematic manner

3. One who engages in the act of rejecting or discarding objects, often to declutter or simplify their surroundings

Etymology: "Discarder" is a plain formation: the verb "discard" with the agent suffix "-er," which marks a person or thing that performs the action. A discarder, then, is simply one who discards, the person doing the throwing away. The verb underneath is the more interesting part of the story. "Discard" carries the sense of casting off a card from one's hand in a game, and the broader sense of getting rid of something no longer wanted grew out of that. Attaching "-er" to a verb in this way is one of English's most productive patterns, which is why the word needs no special history of its own: it is built on the spot from a familiar root and a familiar ending.

Synonyms: thrower away, eliminator
