silver-bearing jarosite (mineral)
Etymology
'argentojarosite' originates from the composite formation of the prefix 'argento-' (from Latin 'argentum', meaning 'silver') combined with 'jarosite' (the name of a sulfate mineral).
'jarosite' was named after the Spanish locality 'Jaroso' and the mineral-name suffix '-ite'; 'argentojarosite' is a later mineral-name coinage formed by prefixing 'argento-' to indicate the presence of silver.
Initially, the components signified 'silver' (argento-) and the mineral 'jarosite'; the combined coinage has retained the meaning 'a silver-bearing jarosite mineral' in modern usage.
