A riddle is, of course, a verbal puzzle: an enigmatic statement, description or question posed by one person to another, or to a group, who have to guess the answer. We use the term loosely for more than one kind of puzzle. However, the riddle proper relies on imagery for its effects; often quite poetic imagery.
1
I am within as white as snow,
without as green as herbs that grow;
I am higher than a house,
and yet am lesser than a mouse.
2
Old Mother Twitchett had but one eye,
And a long tail which she let fly;
And every time she went over a gap,
She left a bit of her tail in a trap.
3
Though of great age,
I'm kept in a cage,
Having a long tail and one ear,
My mouth it is round,
And when joys do abound,
O, then I sing wonderful clear.
4
I have a penis on yonder hill,
I keep him for a wonder,
And every time the penis do crow,
It lightens, hails and thunders.
I hope this helps!<3
