Sedulous is an adjective that means involving great effort and perseverance.
Our word of the day is evolved from the Latin words se dolus (say DOE loose) which mean ‘without guile.’ Over time this evolved into a single word sedulo (say DOO low) meaning ‘diligently’ or ‘sincerely.’
Marcy is a great asset to the company. She’s a sedulous employee who works long and hard to make sure she gets things done right.
Once again, sedulous is spelled SEDULOUS.
