'atomless' originates from the word 'atom,' which comes from the Greek word 'atomos,' meaning 'indivisible.' The suffix '-less' is used to denote 'without.'

'Atom' changed from the Greek word 'atomos' to the Latin 'atomus,' and eventually became the modern English word 'atom.' The suffix '-less' was added to form 'atomless.'

Initially, 'atom' meant 'indivisible particle,' but 'atomless' evolved to mean 'lacking atoms.'
