"Agentic" is an adjective that got sold as a noun, and most of the confusion around it comes from that one grammatical mistake.
You cannot buy agentic AI, in the same way you cannot buy fast. Fast describes a car. Agentic describes how much of the deciding a system does without you. It is a measurement, and the useful question is never whether a system is agentic. It is how agentic, at which points, and what happens at those points when it gets it wrong.
Once you look at it that way, a lot of vendor language becomes legible. And so does the reason a good share of these projects end badly: companies buy at one point on the scale and deploy as though they had bought a different one.
The Word Comes From Agency, and That Is the Whole Idea
Agency, in the ordinary sense, is the capacity to act on your own behalf. Applied to software, it describes systems that pursue a goal by choosing their own actions rather than executing prescribed ones.
