This is a new edition of the Oxford Primary School Dictionary. It is a core OUP dictionary for children aged 8 and over and specially written for home and school use. Now fully revised and updated, with a new design, this dictionary is clearer and easier to use. New additions include a large number of headwords for the first time and many derivatives defined for the first time, such as naturally, strongly and squarely. Usage notes have been expanded, for example on sew/sow, and spaceman and spacewoman, and American equivalents are given for high-profile words such as sidewalk and hood (of a car). New vocabulary includes words such as byte, mad cow disease, road rage and millenium, and all plurals, verb and adjective forms are written out in full. Pictures are specially drawn in whole sentences to show how words are used in context and idioms have also been added, for example, neck and neck, in dire straits and pipe dream. Information boxes give the origins of words and give advice about usage.
