'analogousness' originates from English, specifically from the adjective 'analogous' with the suffix '-ness' added to form a noun, where 'analogous' comes from Greek 'analogos' meaning 'proportionate' or 'corresponding'.

'analogousness' was formed in English by adding the noun-forming suffix '-ness' to 'analogous', which itself came from the Greek word 'analogos' via Latin and French.

Initially, it meant 'the state of being analogous or similar', and this meaning has remained consistent in modern usage.
