Etymology Origin:
The word accuracy traces back to Latin accuratus, meaning "done with care," derived from ad- (toward) + cura (care). It entered English in the 16th century, originally describing meticulous attention to detail. Over time, it evolved to emphasize correctness and precision, particularly in scientific and technical contexts. The morphemes reflect a logical progression: "directed toward care" → "careful execution" → "freedom from error."
