(noun) A thing that is helpful or beneficial.

Fun Fact
Originally associated with blessings or requests in Old English and Norse mythology, a “boon” once referred to a favor granted by a king or god. Today, it’s still used to describe anything that feels like a fortunate benefit—whether it’s a job perk, a technological breakthrough, or a surprise day off.
SEJ-uh-lus
(adjective) Showing dedication and diligence; persistent and hardworking.
Her sedulous efforts to master the violin resulted in a flawless performance at the competition.
Mid-16th century: from Latin “sedulus,” possibly from “sedulo” meaning “zealously,” from “se-” (without) + “dolus” (guile or deception).
Fun Fact
Sedulous suggests more than simple hard work—it implies careful, persistent attention to detail over time. The Latin root connects to “without guile,” suggesting honest, straightforward effort rather than shortcuts or tricks. Victorian self-help books praised sedulous application as the path to success, contrasting it with flashy talent or lucky breaks. Scientists describe sedulous research that requires years of patient data collection. Unlike “diligent,” which can sound dutiful, sedulous carries a voluntary quality—you’re sedulous because you care about excellence, not just because someone’s watching. The word fell somewhat out of fashion but remains perfect for describing that specific combination of persistence, care, and dedication that produces mastery.
