Saner → It is formed from "sane" (from Latin "sanus", meaning healthy or sound) and the suffix "-er" (meaning one who). The word "saner" refers to one who is more healthy or sound in mind compared to another.
Think of someone who is 'more healthy' or 'sound' in their thinking — 'sane' means healthy, and '-er' indicates a person who is more so.
