sedulous (adj.)

"diligent in application or pursuit of an object," 1530s, from Latin sedulus "attentive, painstaking, diligent, busy, zealous," probably from sedulo (adv.) "sincerely, diligently," from sedolo "without deception or guile," from se- "without, apart" (see se-) + dolo, ablative of dolus "deception, guile," which is cognate with Greek dolos "ruse, snare." Related: Sedulously; sedulousness.
