Etymology
the word 'endorse' originates from the medieval latin term indorsare, which itself is a compound of the latin prefix in- (meaning 'on') and dorsum (meaning 'back'). this literal sense of 'writing on the back' of a document was the original meaning, specifically referring to signing a cheque or legal paper on its reverse side. over time, this tangible act of putting one's name on the back as a sign of authorization evolved metaphorically. the modern, more abstract meaning of expressing public support or approval stems from this idea of backing something with one's name and reputation, as if signing it.
