How is "particular" best characterized?

The term "particular" is best characterized as being "different from the usual or normal." This definition highlights a sense of specificity or uniqueness associated with the word. When something is described as "particular," it often implies that it possesses distinct characteristics that set it apart from a broader category or from what is considered typical. This semantic nuance captures the essence of the term, as it conveys an emphasis on individual or unique qualities rather than general or common ones.

In contrast, the other options do not align with this meaning. For instance, describing something as "common and ordinary" suggests a typicality that contradicts the uniqueness implied by "particular." Similarly, the notion of being "uniform across all instances" implies a lack of distinction, which opposes the individuality inherent in "particular." Finally, "frequently seen" indicates prevalence rather than uniqueness, failing to capture the essence of something being special or distinctive. Thus, the most fitting characterization is that of being "different from the usual or normal."
