But the giant "M" is a "representation" and a "spokesman," like it is in Hebrew.
This is a folk etymology. It ignores the actual origin of the term, where a single block of type (a logotype) was used for some whole words in early printing presses instead of using separate letter blocks which led to words represented by symbols in typography, and instead draws a superficial similarity between the Hebrew term for ‘representative’ and contorts it into a sense of ‘representation’ in reference to the modern use of logos.
