Comics (via Latin, from the Greek "Κωμικ-ός", kōmikos, of or pertaining to "comey", from kōmos "revel".) is a graphic medium in which images are utilised in order to convey a sequential narrative. It is the sequential nature of the pictures, and the predominance of pictures over words, that distinguish comics from picture books, though there is some overlap between the two genres. Most comics combine words with images, often indicating speech in the form of word balloons, but wordless comics, such as The Little King, are not uncommon. Words other than dialog, captions for example, usually expand upon the pictures, but sometimes act in counterpoint.
