What does floatation mean?
Floatation is a rare noun and a less common spelling of flotation. It can denote the act of floating or the condition of remaining on a liquid surface, as when a buoy, cork, or layer of oil stays afloat. In technical usage, the word also refers to the separation of mixed particles in a liquid according to whether they float, a method central to mineral concentration and commonly called froth flotation. Because flotation is the established modern spelling, floatation often sounds marked, dated, or regional rather than neutral. Nevertheless, it remains intelligible and can be useful when a writer deliberately echoes an older spelling or discusses the history of the word family. Floatation should therefore be understood not as a separate concept from flotation, but as a spelling variant with essentially the same range of meanings.

"Engineers monitored the floatation of the buoy as the storm intensified."
"The floatation of the capsule remained stable despite the choppy water."
"The ore underwent floatation before the valuable concentrate was collected."
The regular plural is possible but rare in practice, partly because flotation is normally preferred.
"Early experiments documented the floatations of oil and water in separate vessels."
A word can keep a buoy on the water and help separate valuable ore; floatation can do both.

Where does floatation come from?
Floatation is an English alternative spelling of flotation, formed from the base float plus the noun-forming suffix -ation. The base comes through Middle English from Old French floter, meaning “to float,” while the -ation formation expresses an action or process. Its close relatives float, floater, and afloat preserve the same root, and the difference between floatation and flotation reflects spelling history rather than a distinction in meaning.
