Which term is used to describe something that is blatant or shameless?

The term "arrant" is used to describe something that is blatant or shameless, often in a negative context. It conveys a sense of extreme or utter quality, usually referring to something that is unequivocally bad or wrong. For example, an "arrant fool" suggests not just a fool, but an exceptionally foolish one, emphasizing a sense of blatant behavior or attitude.

In contrast, "errant," which may seem similar, typically refers to something that deviates from the proper course or standard, rather than being unapologetically blatant. "Apposite" relates to being relevant or appropriate, which does not convey any sense of shamelessness. "Anodyne" describes something that is soothing or alleviating pain, and has no direct correlation to behavior that is blatant or shameless. Thus, "arrant" stands out as the term that aptly captures the essence of something that is both blatant and shameless.
