Definition of sanely

The word "sanely" has its roots in the 15th century Latin word "sanus," meaning "healthy" or "sound." From this Latin root, the Middle English word "sane" emerged, referring to someone with a healthy or sound mind. Over time, the word "sane" was used to contrast with its opposite, "insane," meaning not mentally well. Eventually, the adverb "sanely" was derived from "sane," meaning in a sane or rational manner. In the 17th century, "sanely" gained its current meaning, describing something that is done or thought of in a reasonable, sensible, or intelligent way. Today, the word is commonly used to indicate that someone's actions or decisions are guided by good judgment and a stable mind. The connection between the Latin "sanus" and the word "sanely" highlights the importance of maintaining mental health and rational thinking in everyday life.
