What does buoyant mean?
"Buoyant" describes something that floats — literally, like a cork or life jacket held up by water — but its reach extends well beyond physics. Applied to people, it characterizes someone whose spirits stay high even under pressure: cheerful, optimistic, and hard to keep down. Economists and journalists use it of markets, housing, and trade to signal robust, active conditions rather than sluggishness. The word carries an unmistakably positive connotation in all its figurative uses; nobody calls a recession buoyant. It derives ultimately from Spanish "boyante," from "boya" (a buoy), which traces back to Latin "boia," a leather strap or collar — the same root that gives us "buoy" itself. That lineage makes the word doubly apt: both the object held afloat by a rope and the person held aloft by good cheer share a common thread. Useful whenever you want to suggest lightness, resilience, or upward momentum with a single adjective.
Able to float or rise to the surface in a liquid; kept afloat by buoyancy.
"The buoyant raft carried them safely across the bay."
Cheerful, optimistic, and not easily discouraged.
"Her buoyant personality made her a favorite among colleagues."
(Of trade, markets, or economies) strong, active, and showing sustained growth.
"Housing demand remained buoyant throughout the spring."
Especially common in British financial journalism.
The same Spanish-derived root behind "buoyant" also gave us the word for the flexible leather hose firefighters once used to douse flames — proof that staying afloat and staying flexible come from the same place.

Etymology of buoyant
"Buoyant" entered English in the early 17th century, borrowed from Spanish "boyante," the present participle of "boyar" (to float), derived from "boya" meaning a buoy. "Boya" itself comes from Latin "boia," denoting a leather band or fetter — the original buoys were markers tethered by such straps. Its cognates include "buoy" and "buoyancy," all descending from that same Latin source.

How buoyant is actually used
Register is neutral-to-formal. The literal floating sense appears most often in physics and everyday description of objects on water; the figurative senses (mood, markets) are very common in journalism and business writing. In British English especially, describing a market as "buoyant" implies healthy, sustained activity rather than a brief spike.
Easily confused with buoyant
"Boyant" is a common misspelling of "buoyant" — the correct spelling contains "u" after "b."
