sane etymology

Etymology

The word "sane" derives from the Latin word "sanus," meaning "sound, healthy, or of good sense."

Meaning

In modern usage, "sane" refers to someone who is mentally healthy, rational, and free from delusions or hallucinations. It implies a state of mind that is characterized by clear thinking, good judgment, and emotional stability.

Origin

The Latin word "sanus" is related to the Proto-Indo-European root "*seh₂-," which means "to be well, healthy, or strong." This root is also found in words such as "sanitary," "salubrious," and "salve."

The word "sane" entered English in the 14th century. It was initially used to describe physical health but gradually came to be applied to mental well-being as well. By the 17th century, "sane" had acquired its current meaning, referring to a state of sound mind.
