Buoyant works across three registers: physical (floats in water), emotional (resilient optimism), and economic (rising prices or markets). All three share the same root image of rising rather than sinking. In casual speech, 'upbeat' or 'cheerful' often reads more naturally than buoyant for the emotional sense.
'Buoyancy' is the noun ('the buoyancy of the life jacket', 'the buoyancy of the market'). A common spelling error is bouyant — note the correct order: b-u-o-y-a-n-t, not b-o-u-y-a-n-t.
From Spanish boyar ('to float'), from boya ('buoy'), which came into English via French in the late 16th century (first recorded c. 1578). The figurative sense of resilient cheerfulness emerged in the early 19th century, extending the image of floating on difficulties rather than being pulled down by them.
