Serger:
An overlock is a kind of stitch that sews over the edge of one or two pieces of cloth for edging, hemming, or seaming. Usually an overlock sewing machine will cut the edges of the cloth as they are fed through (such machines being called “sergers” in North America), though some are made without cutters. [Wikipedia]
As my wife is a tailor, I’ve suddenly been introduced to this word several times in the last few years. Only recently did I learn the spelling, though.
