'acoemeti' originates from Greek, specifically the word 'akoimetoi,' where 'a-' meant 'not' and 'koimetoi' meant 'sleeping.'

'akoimetoi' transformed into the Latin word 'acoemeti,' and eventually became the modern English word 'acoemeti.'

Initially, it meant 'those who do not sleep,' referring to their practice of continuous prayer, and this meaning has largely remained the same in modern usage.
