The word "permanent" refers to something that lasts or remains unchanged for a long time, or indefinitely. It suggests a state or condition that is not intended to be temporary or fleeting, but rather enduring and lasting over time. For example, a permanent residence would imply a home that someone intends to live in for an extended period, as opposed to a temporary living arrangement.
The word "permanent" comes from the Latin "permanens," which is the present participle of "permanere," meaning "to remain through" or "to stay." This word is derived from "per-" meaning "through" and "manere" meaning "to stay."
