Fun Fact
“Accretion” comes from the Latin accretio, meaning “growth” or “increase.” The term is widely used in science, such as in astronomy, where it describes the process of material gathering around a celestial body. It also has metaphorical applications, often symbolizing the slow but steady buildup of ideas, habits, or relationships.
(noun) Excessive confidence or boldness; rashness in the face of danger or opposition without regard for consequences.
The junior analyst had the temerity to challenge the CEO’s projections in front of the entire board — and was proven right six months later.
Temerity derives from the Latin temeritas, meaning “rashness” or “blind chance,” rooted in temere — “rashly” or “by chance” — suggesting action taken without looking, in the dark, without regard for what might be coming. It entered English in the 15th century carrying its full Latin sense of dangerous, heedless boldness — the kind that mistakes the absence of fear for the presence of wisdom.
