# DictionaryLookup

 DictionaryLookup[patt] finds all words in an English dictionary that match the string pattern patt. DictionaryLookupgives only the first n words found. DictionaryLookupfinds words in the language specified by lang.
• No word stemming is done by default, so words like "jump", "jumps", and "jumping" appear separately.
• By default, words appear as they would within a sentence. Setting the option IgnoreCase->True retrieves words whose letters appear in different cases.
