Etymology

Origin of asymmetry

First recorded in 1645–55, asymmetry is from the Greek word asymmetría lack of proportion. See a- 6, symmetry

Explanation

Asymmetry exists when the two halves of something don't match or are unequal. The American flag is an example of asymmetry. If you understand symmetry, you're on your way to understanding asymmetry. Symmetry means that the parts of something are equal or match: if both halves of a house look exactly the same, that's an example of symmetry. If the sides are different, that's asymmetry. This concept can apply to relationships too. If one friend is taking advantage of the other, this is an asymmetrical relationship because it's not equal or fair. When you see the word asymmetry, think unequal or unbalanced.
