What is a synonym for "persnickety"?

The term "persnickety" describes someone who is overly particular or fussy about details, often focusing on trivial matters. A synonym that aligns with this definition is "meticulous," which indicates a person who pays great attention to detail and is careful about how things are done. Both words emphasize a high level of concern for precision and accuracy, reflecting a similar mindset of being finicky about certain aspects.

The other choices do not share this level of specificity regarding attention to detail. "Carefree" suggests a lack of worry or concern, which is the opposite of being persnickety. "Efficient" refers to getting things done effectively with minimal waste of time or resources, but it does not capture the notion of fussiness or particularity. "Generous" pertains to a willingness to give more of something than is necessary or expected, which is unrelated to the characteristic of being finicky or detail-oriented. Therefore, "meticulous" stands out as the correct synonym for "persnickety."
