'analogia' originates from Latin, specifically the word 'analogia', which itself comes from the Greek word 'ἀναλογία' (analogia), where 'ana-' meant 'according to' and 'logos' meant 'ratio' or 'proportion'.

'analogia' was used in Latin and Greek to refer to proportional relationships or analogies, and the term has been adopted into English, especially in academic contexts, to refer to analogy or similarity.

Initially, it meant 'proportion' or 'correspondence', but over time it evolved into its current meaning of 'analogy' or 'similarity, especially in reasoning or language'.
