Etymology
Noun
ombudsman (plural ombudsmen)
An appointed official whose duty is to investigate complaints, generally on behalf of individuals such as consumers or taxpayers, against institutions such as companies and government departments.

Usage notes
• This term is derived from Swedish, in which language the suffix -man is not always gender-specific. Nevertheless, the words ombud, ombuds, ombudsperson, and ombudswoman have been coined to remedy the perceived gender-specificity of ombudsman in English.
