While working as a sub-editor, an erudite colleague once pointed out to me that while we say – and more often write – the word swathe (which rhymes with lathe) as a noun, it is properly used only as a verb.
Furthermore, its noun form is swath (which rhymes with cloth) … tell that to newsreaders on radio and television or the average punter!
A little dictionary checking proved that my articulate colleague was pretty much spot on, with the tiny – and rare – exception that the only noun form for swathe refers to “a wrapping or bandage”.
Should you still doubt this revelation, Grammarist has an excellent, simple explanation to assuage your concerns.
