Etymology

Origin of contrary

First recorded in 1200–50; Middle English contrarie, from Anglo-French, from Latin contrārius; equivalent to contra ¹ + -ary

Explanation

Use contrary when two things are exactly opposite or entirely different. If something is contrary to something else, it is opposed to or against it. A contrary child is one who opposes people in authority. As a noun, the contrary means the opposite, as in "We will not give up; on the contrary, we will fight with all our power." The adjective contrary derives from Latin contrarius ("opposite, opposed") from contra ("against").
