Morphology

buoy + up

The meaning 'to keep afloat; to support' is directly derivable from combining 'buoy' (to keep afloat, uplift, or encourage) with the particle 'up' (indicating upward movement or strengthening), so the composite sense is compositional. This motion/causative + particle pattern is common and predictable, so a B1 learner who knows both constituents would readily infer the MWE meaning.

Etymology

Buoy up comes from the real buoys and floats that keep boats or people on the water. So to 'buoy up' something means to keep it 'afloat' and stop it from sinking.
