'sepulture' originates from Old French, specifically the word 'sepulture', where 'sepul-' meant 'grave' and '-ture' was a suffix indicating action or process.

'sepulture' changed from the Old French word 'sepulture' and eventually became the modern English word 'sepulture'.

Initially, it meant 'the act of burying', and this meaning has largely remained the same in modern usage.
