The word "stably" is derived from the adjective "stable", which dates back to the early 13th century. The term originated from the Old French word "stable" which means firm, fixed, steadfast. It can be traced further back to the Latin word "stabilis" meaning firm, steadfast, or durable. The root word "stabilis" comes from the verb "stare", which means to stand. Over time, the adjective "stable" developed into the adverb "stably", indicating something done in a stable or firmly established manner.
