The word "decided" refers to the act of making a clear and firm choice about something. It implies that someone has reached a conclusion after consideration and is confident in that conclusion. When someone is described as "decided," it often means their thoughts, beliefs, or decisions are strong and unwavering.
The word "decided" comes from the Latin root "decidere," which means "to cut off" or "to settle." The prefix "de-" suggests a fullness or completion, while "caedere" means "to cut." Over time, it evolved into the Middle English term "deciden," leading to its current form.
