'bottomless' originates from Old English, specifically the word 'botmleas,' where 'botm' meant 'bottom' and '-leas' meant 'without.'

'botmleas' transformed into the Middle English word 'botomles,' and eventually became the modern English word 'bottomless.'

Initially, it meant 'without a bottom,' but over time it evolved into its current meaning of 'inexhaustible or unlimited.'
