'self-perception' originates from the combination of 'self,' meaning 'one's own person,' and 'perception,' from Latin 'perceptio,' meaning 'the act of perceiving.'

'perceptio' transformed into the French word 'perception,' and eventually became the modern English word 'perception.'

Initially, 'perception' meant 'the act of perceiving,' and over time it evolved to include the understanding of oneself.
