ASSIDUOUS in Context
“No entombed Egyptian pharaoh has had the stunning and star-studded afterlife of King Tut…. It’s all due to a stroke of good luck. Which would include an amazing dearth of tomb-pillaging, an intrepid archeologist and his team, plus meticulous documentation from National Geographic. Also, an assiduous PR campaign for various touring exhibits celebrating the life and possessions of the ‘boy king.’” — Jim Sullivan, WBUR.org (Boston, Massachusetts), 13 July 2022
Did You Know?
While assiduous means “showing great care, attention, and effort,” and in some situations may be an appropriate substitute for careful, it’s got a bit more oomph than careful in that it suggests a dogged or tireless persistence. If you are assiduous in your efforts (or work, research, analysis, training, preparations, etc.) for example, it’s implied that you’re in it for the long haul, or that you have the ability to “sit with” a task or challenge for a considerable amount of time. This makes sense given that assiduous comes from the Latin verb assidēre, meaning “to sit beside.”
