What is the origin of unintentional?
Let's start with the root of the word: intend.This comes from the Old French word intendre, meaning "to direct one's attention to." It's a construction from in + tendre, which literally means "to stretch towards." The idea was that you stretched towards your goal or objective.The noun form is intent, which is the basis for the adjective intentional. Unintentional comes from that.
