'antimonide' originates from English chemical nomenclature built from 'antimony' (the name of the element) plus the suffix '-ide' (used for binary compounds); 'antimony' itself comes from Old French 'antimoine' and Medieval Latin 'antimonium'.

'antimony' changed from Old French 'antimoine' and Medieval Latin 'antimonium' and eventually became the modern English 'antimony'; the compound-forming suffix '-ide' (from French/Latin usage in chemistry) was later appended to create 'antimonide' in modern chemical terminology.

Initially names related to 'antimony' referred to the element or substances of antimony; over time the derived term 'antimonide' came to mean specifically a binary compound containing antimony combined with another element.
