'strictly-managed' originates from the combination of 'strictly' and 'managed'. 'Strictly' comes from the Latin 'strictus', meaning 'tight' or 'drawn together', and 'managed' is derived from the Italian 'maneggiare', meaning 'to handle'.

'strictus' transformed into the Old French 'estrict', and eventually became the modern English word 'strict'. 'Maneggiare' evolved into the French 'maneger', and eventually became 'manage' in English.

Initially, 'strictly' meant 'in a tight manner', and 'manage' meant 'to handle'. Over time, 'strictly-managed' evolved to mean 'controlled with strict rules'.
