'antimoniferous' originates from New Latin, specifically the combination of 'antimony' and the suffix '-ferous', where '-ferous' meant 'bearing' (from Latin 'ferre' meaning 'to bear').

'antimoniferous' changed from Neo-Latin formations combining 'antimoni-' (from 'antimony') with '-ferous' and eventually became the modern English adjective 'antimoniferous'.

Initially, it meant 'bearing or containing antimony', and this meaning has largely remained the same in modern usage.
