Not having someone or something to represent or speak for you.
Many voices in the community feel unrepresented in local government decisions.
Unrepresented → It is formed from "un-" (meaning not) and "represented" (from Latin "repraesentare", meaning to present again or to show). The word "unrepresented" means not being shown or presented, indicating a lack of representation.
Think of 'not' ('un-') being 'shown' ('represented') — that's why unrepresented means not being shown or lacking representation.
