The English word "logo" was shaped by the Hebrew usage, not the Greek.
This is simply wrong. The English word ‘logo’ (originally as ‘logotype’) is derived from the Greek word ‘logos’, from the plain sense of its meaning of ‘word’, wherein a logo is representative of a name or word. The etymology of the term as it relates to typography is well documented, and there was never an intent that logos serve as ‘messengers’ when the term was coined.
