asymmetry

ay-SIM-uh-tree/ˌeɪˈsɪmətri/

Lack of balance or matching between opposing sides or parts.

The leaf's unequal lobes create noticeable asymmetry across its central vein.

Etymology

Measuring together gives the idea of parts sharing a common measure or proportion; the negative prefix denies that agreement. As symmetry came to include mirror correspondence, asymmetry also described the absence of that balance.
