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

'overvalue' changed from the Middle English word 'overvalewen' and eventually became the modern English word 'overvalue'.

Initially, it meant 'to assign too high a value to something', and this meaning has largely remained the same in modern usage.
