noun
backward bend; reverse warp; back bow
1. backward bend; reverse warp; back bow

Composed of 逆(ぎゃく) (reverse, opposite) and 反(そ)り (warp, bend, curve). The 反(そ)り undergoes rendaku (voicing) to become ぞり. This term is used across several domains: in woodworking and construction, it describes unwanted warping of materials in the wrong direction; in physical activity, it describes arching the body backward.
