An affix riddle is a specific type of riddle that clues the target word by describing multiple, possibly overlapping parts of the word separately. Usually the beginning (prefix), the middle (infix), and the end (suffix) of the word are described. Sometimes referred to as Riley riddles.
An affix riddle is a specific type of riddle that clues the target word by describing multiple, possibly overlapping parts of it. Usually the beginning (prefix), the middle (infix), and the end (suffix) of the word are described, with an oblique clue towards the whole word's meaning as the final part of the puzzle.
Here on PSE you might also see this type of riddle colloquially referred to as 'a Riley riddle', as the first riddle posted on the site to use this formulation was created by the user @Riley: My prefix is food, my suffix is rude. Our (linguistically somewhat inaccurate) practise of calling all the word parts "affixes" also comes from this puzzle.
