Results: Clue writing contest 1969 Coalport Ciaran Daly, Cork, Ireland Fuel tanker's left China Fuel = COALtanker's left = PORT China = definition If Coalport is unfamiliar as a word, its main meaning is a type of porcelain, produced at a Shropshire village of the same name, mainly in the 19th century. It was often decorated with colourful moulded patterns, often in floral designs. In this seemingly simple clue, dividing the word into its most obvious parts, there are a couple of subtleties. The first is 'fuel tanker' needing to be split up and 'tanker' being part of 'tanker's left' ('tanker' being a kind of ship), and another is 'China' apparently in its geographical meaning.
