'chemically-bonded' originates from the word 'chemical,' which comes from the Greek word 'khēmeia,' meaning 'alchemy,' and 'bond,' which comes from the Old English 'bonda,' meaning 'to bind.'

'Chemical' evolved from the Greek 'khēmeia' to the Latin 'chimicus,' and eventually became 'chemical' in modern English. 'Bond' evolved from the Old English 'bonda' to the modern English 'bond.'

Initially, 'chemical' referred to alchemy, but now it refers to substances and reactions. 'Bond' originally meant 'to bind,' and this meaning has largely remained the same.
