'overvalue' originates from the prefix 'over-' meaning 'excessively' and the word 'value' from Latin 'valere' meaning 'to be strong or worth'.

'overvalue' changed from the Old French word 'valuer' meaning 'to value' and eventually became the modern English word 'overvalue'.

Initially, it meant 'to assign a value', but over time it evolved into its current meaning of 'assigning too high a value'.
