'aisleless' originates from the English word 'aisle', combined with the suffix '-less', where 'aisle' meant 'a passage between rows of seats' and '-less' indicates 'without'.

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

Initially, 'aisle' meant 'wing of a building', but over time it evolved into its current meaning of 'a passage between rows of seats'.
