'strictly-made' originates from the combination of 'strictly' and 'made', where 'strictly' is derived from Latin 'strictus', meaning 'tight' or 'drawn together', and 'made' is the past participle of 'make', from Old English 'macian'.

'strictly' evolved from the Latin 'strictus' through Old French 'estrict', and 'made' from Old English 'macian', eventually forming the modern English term 'strictly-made'.

Initially, 'strictly' meant 'tightly' or 'closely', and 'made' referred to 'constructed'. Together, they evolved to mean 'constructed with strict adherence to standards'.
