Example of Iconicity

Iconicity is generally referred to as a conceptual association between word and image of the word. The modern form of iconicity is more likely to be a trademark image, some form of brand image, or a use of a part of a name as an icon. The relationship between icon, image, and verbal association is the 'iconicity' factor.

Examples of Iconicity:

The Apple logo: Apple is the name, the image is of an apple.
The Wall Street bull, referring to a bull stock market, is a typical association in iconicity.
Special K, the Kellogg trademark, is a basic iconic association of the letter K and the product.
