The sputterer in the corner was trying to fix the old engine, but it kept making strange noises.
Sputterer → It is formed from "sputter" (originating from Middle English *sputtren*, meaning to spit or emit in small drops) and the suffix "-er" (meaning a person who). A sputterer is a person who emits or spits out in small drops or bursts.
Think of someone who 'spits out' ('sputter') sounds or liquids in small bursts — that's what a sputterer does.
