Those selling on eBay would do well to mind their language, a study suggests.
Certain words, coupled with good spelling and grammar, are key to achieving high sale prices.
Researchers from Birmingham City University found "men's" watches sold for an average of £30 ($62) while those labelled for "gent's" went for £70 ($146).
"Authentic" fragrances sold for an average of £34, while "genuine" ones only went for £21 ($43).
A watch with water "resistance", meanwhile, typically sold for 50 per cent more than a water "resistant" watch.
