Chocoholic is one of a number of recent words formed by analogy with alcoholic, a word with an interesting history of its own. Alcohol originally came from two Arabic words: al, or 'the', and kohl, the black eyeliner widely used in Arabic countries. How this came to refer to alcohol is a bit obscure, but the suffix -ic was added at some stage to refer to a person addicted to alcohol. Since then, the word has been chopped about, and the suffix -oholic or -aholic is now added to other words to refer to various kinds of addiction.
The commonest of these is workaholic, someone unable or unwilling to stop working. Chocoholic, is another common variant of 'alcoholic', and can be spelled 'chocaholic' or even 'choc-a-holic'. Many young (and not so young) people are textaholics or addicted to text messaging.
The -oholic suffix is often used to generate new words for humorous effect. For example, a driver unwilling to leave his car behind has been described as a 'diesel-holic'. In addition, it has been said of the Rangers manager Dick Advocaat that he is a 'football-holic'.
