Which term refers to someone who is meticulous and pays close attention to detail?

The term that describes someone who is meticulous and pays close attention to detail is "fastidious." This word is often used to characterize individuals who are particularly careful about their standards and require precision in their work or surroundings. A fastidious person is not only attentive to detail but also tends to be very particular about how things are done, striving for perfection and high quality in their efforts. This trait is important in various fields, including editing, craftsmanship, and any task where accuracy is paramount.

In contrast, the other terms do not convey the same meaning. For example, "fawn" often refers to a behavior where someone shows excessive affection or flattery, typically toward someone of higher status. "Fluke" describes an event that is unlikely to happen or a stroke of luck, and does not relate to attention to detail. "Harbinger" signifies a person or thing that announces or signals the approach of another, hence it does not align with the concept of meticulousness. Therefore, "fastidious" is the most appropriate choice for describing someone who is very attentive to detail.
