'self-coherence' originates from the combination of 'self,' meaning 'one's own person,' and 'coherence,' which comes from Latin 'cohaerentia,' meaning 'sticking together.'

'cohaerentia' transformed into the French word 'cohérence,' and eventually became the modern English word 'coherence,' which combined with 'self' to form 'self-coherence.'

Initially, 'coherence' meant 'sticking together,' but over time it evolved to mean 'logical consistency,' which is retained in 'self-coherence.'
