'physical' originates from Greek, specifically the word 'physikos,' where 'physis' meant 'nature.' 'Level' originates from Latin, specifically the word 'libella,' where 'libra' meant 'balance.'

'physical' changed from the Greek word 'physikos' and eventually became the modern English word 'physical.' 'Level' transformed from the Latin word 'libella' and eventually became the modern English word 'level.'

Initially, 'physical' meant 'pertaining to nature,' but over time it evolved into its current meaning of 'relating to the body or material world.' 'Level' initially meant 'balance' and evolved to mean 'a specific height or line.'
