A logo is a unique combination of elements—usually graphics and type—that creates a reproducible and recognizable design. Depending on the brand and the context, these elements can also exist on their own.

A logomark is the graphic element, symbol, or icon (for example, Nike’s Swoosh, Starbucks’ siren, or Apple’s apple) that represents the company or brand.

A logotype, which can also be known as a wordmark (although usually only if it’s made up of just one word), is a specific lockup of the brand’s name. It can be something as simple as a customized setting of a typeface (for instance, with custom kerning), an altered version that actually changes the letterforms’ outlines, or a completely bespoke piece of lettering.

Combining a logomark and logotype together forms a logo, although it’s fair to say that the term “logo” is often used to refer to these individual elements, too.
