alderman
Synonym discussion
Sense: noun/1
Alderman, councillor, and council member all refer to people who work in local government, but they are not always exact substitutes. In many North American cities, an alderman is an elected person on the city council, often representing one district or ward. Councillor is the broader British and Commonwealth term for a local elected member. Council member is a neutral modern label that avoids the older title alderman. Mayor is different again: the mayor leads the city government, while an alderman is one member of the governing body. You can elect an alderman to represent a district, but that does not make the person the mayor.

Etymology
Alderman comes from Old English parts meaning an older or senior man. The word first referred to a person of high standing in a community, and later became a formal title in local government. That older idea of senior rank still helps explain why the historical British and Irish sense refers to a councillor with higher standing than ordinary members.
