Webster's New World
This dictionary is out of print and as of 23 June 2015 there was no plan by the publisher to come out with a new edition.
However, we do recommend the
Oxford Essential Dictionary (paperback) with CD
"This is a very basic children's dictionary. Its greatest value is it keeps the definitions short and simple. I use it in my tutoring practice when a very basic definition is needed. I also recommend it to young students as their first dictionary." Mary Lewis
