IPA: /kənˈtɛstər/

A person who challenges or disputes the results of a competition, election, or event.

Contester → It is formed from "con-" (meaning together) and "testari" (meaning to witness or testify). The word refers to someone who comes together to challenge or dispute something, often in a formal context.
Think of people 'together' ('con-') trying to 'prove' or 'testify' ('testari') against something — that's why a contester is someone who challenges or disputes.
