'argentino' originates from Spanish, ultimately from Latin 'argentum', where 'argent-' meant 'silver'.

'argentino' developed via Medieval Latin/Old Spanish forms related to Latin 'argentum' (silver) → Medieval Latin 'argentinus' → Old Spanish 'argentino', eventually becoming the modern Spanish adjective and demonym 'argentino'.

Initially related to 'silver' (e.g., 'of silver' or 'made of silver'), the term later came to be associated with places named for silver (such as Río de la Plata) and evolved to mean 'of or from Argentina'.
