The form of a thing that has become present to the intellect.

After learning what a circle means, you possess a concept of a circle. Its acquisition is considered under the first sense, while the concept acquired is considered under the second.
The formulations are closely connected, but the process of acquisition and its result are different aspects of analysis.
