Not only does YourDictionary offer definitions for words, but you can use it as a thesaurus as well. Here's how:
1. Type in a keyword from the clue. For example, if the clue reads: shadowing someone, Fido-style, type "shadow" into the search box.
2. Read through the definitions to see if the answer is included within the definitions themselves.
3. Otherwise, click on the "Thesaurus Synonyms" tab. Are you looking for a verb or a noun? Read through the various definitions and the synonyms provided.
4. In our example, the word we are looking for is a verb-dog. The clue given may not always have a keyword included within to search from. Therefore, it may be necessary to find a more specialized crossword thesaurus.
