The English Talking Dictionary comes with a standard, unabridged dictionary that contains over 250,000 words. When a word definition is provided, it is always accompanied by a sentence using the word in context for each sense / meaning of the word. It even shows you the form of the word (i.e. noun, verb, adjective, etc.). The definitions are clearly written so that they can be understood by all age groups.
InstantTranslate makes it really easy to translate a selection of text in the application you are working in from one language to another language.
