'securely-blended' originates from the combination of 'securely' and 'blended', where 'securely' is derived from the Latin 'securus', meaning 'free from care', and 'blended' comes from the Old English 'blendan', meaning 'to mix'.

'securely' changed from the Latin 'securus' to the Old French 'secur', and eventually became the modern English word 'securely'. 'Blended' evolved from the Old English 'blendan' to the Middle English 'blenden', and eventually became the modern English word 'blend'.

Initially, 'securely' meant 'free from care', but over time it evolved into its current meaning of 'safely'. 'Blended' has largely retained its original meaning of 'mixed'.
