What is the meaning of "insular"?

The term "insular" refers to a narrow or limited perspective, often characterized by a lack of openness to broader ideas or experiences. In many contexts, it describes someone or something that is isolated, either literally by being surrounded by water or figuratively by having a mindset that is not open to outside influences or perspectives.

This aligns perfectly with the chosen answer, which speaks to being "narrowly restricted in outlook or scope." When a person or community is described as insular, it typically indicates a focus on their own interests or cultural norms, often leading to a disconnection from or ignorance of the outside world. Understanding this term can help in recognizing when someone may be resistant to new concepts or experiences due to a limited viewpoint.

The other options imply openness or connection, which contradicts the essence of being insular. For instance, being open to new ideas or experiences would directly oppose the restricted perspective that "insular" embodies, while lacking connection or being broader than usual does not accurately capture the focus on narrowness inherent in the word.
