'overpraise' originates from Middle English, combining 'over-' meaning 'excessively' and 'praise' from Old French 'preisier', meaning 'to value or esteem'.

'preisier' transformed into the Middle English word 'preisen', and eventually became the modern English word 'praise'.

Initially, it meant 'to value highly', but over time it evolved into its current meaning of 'to praise excessively'.
