A rebus is a visual puzzle that presents the reader with an image containing a set of letters or pictures, for example:

FAREDCE

and asks the reader to determine what word or phrase is represented by the image. Usually the phrase uses pictures or letters to represent pieces of the word at a time.

In the above puzzle, the answer is red in the face, as the word RED can be found in-between the letters of the word FACE.

HEAD

HEEL

represents head over heels.
