The word "centrosymmetric" refers to something that possesses a central symmetry or symmetry that is centered around a specific axis. Antonyms for this word could be "asymmetric", "lopsided", "irregular", "unsymmetrical", "crooked", "uneven", "unbalanced", or "disproportionate". These words all describe things that lack symmetry and balance, or have an uneven and irregular shape or form. They are the opposite of centrosymmetric, which implies balance and uniformity, and are often used to describe objects that are imperfect or flawed in some way. As such, they represent a departure from the ideal of perfect symmetry and balance that is associated with centrosymmetry.
