'physician-supervised' originates from the combination of 'physician' and 'supervised', where 'physician' refers to a medical doctor and 'supervised' means overseen or monitored.

'Physician' comes from Old French 'fisicien', and 'supervised' comes from Latin 'supervidere', meaning 'to oversee'.

Initially, 'supervised' meant 'to oversee', and combined with 'physician', it evolved to mean 'overseen by a doctor'.
