'strictly-regulated' originates from the combination of 'strictly' and 'regulated'. 'Strictly' comes from the Latin 'strictus', meaning 'tight' or 'drawn together', and 'regulated' comes from the Latin 'regula', meaning 'rule'.

'Strictly' evolved from the Old French 'estrict', and 'regulated' from the Latin 'regulatus'. Together, they formed the modern English term 'strictly-regulated'.

Initially, 'strictly' meant 'in a tight manner', and 'regulated' meant 'controlled by rules'. Over time, the combined term 'strictly-regulated' came to mean 'controlled by strict rules'.
