ombudsman

This term describes a neutral third party tasked with protecting individual rights against institutional power. It carries a connotation of fairness, impartiality, and administrative oversight, typically operating within government agencies, universities, or corporate sectors to rectify systemic failures. While the word is a countable noun, it is worth noting that in modern usage, the gender-neutral term ombudsperson is frequently employed to avoid the masculine suffix, though ombudsman remains the standard legal and historical title in many jurisdictions.
