alabear

A technical verb meaning to warp or bow, almost always describing wood or boards deforming from humidity or heat — la tabla se alabeó con la humedad. Rare outside carpentry and construction contexts.

• La madera se alabeó por la humedad del sótano. — The wood warped from the basement's humidity.
• Revisa que la tabla no esté alabeada antes de comprarla. — Check that the board isn't warped before buying it.
• El calor puede alabear los tablones si no se almacenan bien. — Heat can warp the planks if they aren't stored properly.

Using alabear for general bending or twisting of any material — it specifically describes the warping deformation typical of wood, not metal bending or fabric twisting, which use different verbs (doblar, retorcer).
