'anaerobiotically' originates from English, specifically from the word 'anaerobiotic,' where 'an-' means 'without,' 'aero' means 'air,' and 'biotic' means 'relating to life.'

'anaerobiotically' was formed from 'anaerobiotic' plus the adverbial suffix '-ally,' and eventually became the modern English word 'anaerobiotically.'

Initially, it meant 'in a way that does not require oxygen,' and this meaning has remained the same in modern usage.
