What is a homophone for councillor?

There isn't a perfect homophone for "councillor," as there's no word that sounds exactly the same but is spelled differently. However, "counselor" is a very close homophone, only differing in the spelling of the final "l".

While they are often used interchangeably, "counselor" typically refers to someone who provides guidance and advice, particularly in a professional context, while "councillor" is more likely to be a member of a council.

So, while not a true homophone, "counselor" is the closest you'll get to a word that sounds the same as "councillor."
