I am a newbie with regard to cryptics and am working hard to improve. I recently saw a crossword that had one-word clues, and the answers could only be a synonym, an antonym or an anagram of the clue. I enjoyed the puzzle and was wondering if this type of puzzle has a name for it, and if there are good online sources for this type of puzzle. Thanks.
I don't know of such crosswords.
There are already dozens of sites for solving anagrams, synonyms and antonyms
Thesaurus.com for the latter.
This site already has a 'quick solve' section.
