Search for an Entry
The dictionary and thesaurus search only for entry words, not the other text in the definitions. Use a keyword or phrase that you would expect to find in a print dictionary or thesaurus. This search always tries to find an exact match to your search words.
Wildcards for Spelling
If you don't know how to spell a word, type a fragment followed by the asterisk(*). For example, type tract* to find the spelling for "tractable." Type *ism for a list of all words ending with those letters.
Uppercase or Lowercase?
The dictionary and thesaurus usually ignore case. Use either upper- or lowercase typing.
Singular or plural?
Dictionary and thesaurus entries are usually singular. If you type in the plural form of a word, for example dogs, the search will find "dog." To ensure the best results, it is preferable to type a singular word.
Punctuation
Use hyphens for hyphenated words (all-star). Other punctuation marks are not valid in a dictionary or thesaurus search.
