'strictly-controlled' originates from the combination of 'strictly' and 'controlled', where 'strictly' comes from the Latin 'strictus', meaning 'tight' or 'drawn together', and 'controlled' from the Latin 'contrarotulare', meaning 'to check against a roll'.

'strictly' evolved from the Old French 'estrict', and 'controlled' from the Old French 'contreroller', eventually forming the modern English term 'strictly-controlled'.

Initially, 'strictly' meant 'tightly' and 'controlled' meant 'checked', but together they evolved to mean 'regulated with strict rules'.
