What does "patent" mean in relation to visibility?

The term "patent" in the context of visibility means something that is obvious or readily visible. When something is described as patent, it suggests that it is clear, evident, or unmistakable, lacking any obscurity. For example, if someone has a patent understanding of a topic, it is evident that they grasp it well, and there is no doubt about their comprehension. This aligns perfectly with the notion of visibility, as something that is patent stands out and is easily perceived or recognized by others.

In contrast, other options like hidden or secret, ambiguous or unclear, and unusual or unexpected do not align with the straightforward or readily observable nature implied by the term "patent." These words denote a lack of clarity or visibility rather than the obviousness that "patent" conveys.
