The moment your feet betray the ground and trust the air instead.
means To jump or spring through the air, propelling yourself off the ground with sudden force.
from From Old English 'hleapan,' to leap or run, a sturdy Germanic word with cousins all over the family — Dutch 'lopen' and German 'laufen' (to run), and 'gallop' itself is a relative through the Frankish side. The same old root gives us 'leapfrog' and the 'leap year,' that calendar hop where the date springs forward an extra day.
