Plural of acrobacy; feats of physical skill and balance performed by acrobats.
From French acrobacie, ultimately from Greek akron (peak, summit) + baino (walk). The original meaning was 'walking on tiptoes' or at the heights of physical capability.
Medieval acrobats were called 'rope dancers,' but the Greek roots 'akron-baino' literally mean 'walking at the heights'—a metaphor that became literal when they actually started performing on raised ropes.
