painstaking
UK: ˈpeɪnzˌteɪkɪŋ | US: ˈpeɪnzˌteɪkɪŋ
adj. showing or requiring great care and effort; meticulous
n. diligent and careful effort
The word "painstaking" originated in the late 16th century, combining "pains" (from Old French "peine," meaning "trouble" or "effort") and "taking" (the act of undertaking). It originally described someone who "takes pains" or goes to great lengths to achieve precision. Over time, it evolved into an adjective emphasizing meticulousness and diligence. The logic reflects the idea of willingly enduring effort ("pains") for thorough results ("taking").
