Usage

What does disproportionate mean? Disproportionate means uneven or out of balance with something in terms of size, ratio, degree, or extent. Disproportionate is the opposite of proportionate. Proportionate is the adjective form of the noun proportion, which refers to the relative size of two or more things. When something is described as disproportionate to something else, it means they are somehow unevenly matched. Example: The military response—striking a dozen different sites with missiles—has been criticized as disproportionate to the act that supposedly provoked it—a single plane briefly entering a no-fly zone.

Etymology

Origin of disproportionate

First recorded in 1544–55; dis- 1 + proportionate

Explanation

If three friends are out having dinner, and one disappears when the check comes, the remaining two end up paying a disproportionate share of the bill. Whenever anything is out of proportion — either too large or too small — it's disproportionate. If you live in New York or Los Angeles or another very expensive city, you probably spend a disproportionate amount of your income on housing — meaning you pay more than you'd expect. If you have a sweet deal somewhere and pay very little in rent, it's still disproportionate — only this time it's less than you'd expect.
