9 December 2011 UTC I ve just dug out my copy of the compact edition little used now because I need the magnifying glass to read it and it does indeed have the two senses that you mention The OED must have removed the soup association when they revised the entries for OED2 They also reversed the order of the senses putting the serving spoon first Collins Millennium Edition has three senses 1 A spoon larger than a dessertspoon used for serving food etc 2 the amount contained in such a spoon 3 a unit of capacity used in cooking medicine etc equal to half a fluid ounce or three teaspoons If the OED is unsure then we have little hope of agreeing on one single definition 08 43
