Logogriph
A logogriph (not to be confused with logogram or logograph) is a form of word puzzle based on the component letters of a key word to be identified, and is derived from Greek λόγος, a word, and γρίφος, a riddle or fishing basket. It generally involves anagrams or other wordplay treatments such as addition, subtraction, omission, or substitution of a letter, and is sometimes arranged in the form of a verse giving hints to the word. The term logogriph is also used for the puzzle type in which a pair of anagrams must be deduced from synonyms (e.g. YELLOW FISH would lead to the answer AMBER BREAM).
