'self-appreciation' originates from the combination of 'self,' meaning 'one's own person,' and 'appreciation,' which comes from the Latin word 'appretiatio,' meaning 'estimation or valuation.'

'appretiatio' transformed into the French word 'appréciation,' and eventually became the modern English word 'appreciation.'

Initially, it meant 'estimation or valuation,' but over time it evolved into its current meaning of 'recognition of worth or value.'
