'aloof' originates from Middle English, specifically the word 'loof,' where 'a-' meant 'on' and 'loof' meant 'windward.'

'loof' transformed into the English word 'aloof,' and eventually became the modern English word 'aloofly' through the addition of the suffix '-ly.'

Initially, it meant 'to keep one's distance,' but over time it evolved into its current meaning of 'distant or indifferent manner.'
