Other forms: logos
A logo is the symbol that stands for a company at a glance. A shape, a colour, and sometimes not even a name.
The best ones work at any size and in one colour, which is why they get so simple over time. Designers distinguish a wordmark, which is the name styled a particular way, from a symbol that stands alone. Companies protect them fiercely as trademarks. The word is short for logotype, and the plural is logos, which is confusingly also a Greek word for reason.
1nounlogoA symbol or design identifying a company or organisation.

1937, a clipping of logogram or a clipping of logotype.
