Intercaste → It is formed from "inter-" (meaning between) and "caste" (from Portuguese "casta", meaning breed or race). The word refers to relationships or interactions that occur between different social or ethnic groups, particularly in the context of caste systems.
Think of interactions that happen 'between' ('inter-') different 'breeds' or 'races' ('caste') — that's what intercaste means.
