'accessless' originates from the English word 'access' combined with the suffix '-less', where 'access' meant 'the ability to approach or enter' and '-less' indicates 'without'.

'access' changed from the Old French word 'acces', which came from the Latin word 'accessus', and eventually became the modern English word 'access'.

Initially, 'access' meant 'approach or entrance', and with the addition of '-less', it evolved to mean 'without access'.
