Etymology

Origin of antitank

First recorded in 1915–20; anti- + tank

Explanation

Anything described as antitank is used to defend against tanks, which are massive, armored vehicles. Antitank armor will withstand a shell from a tank. Tanks are huge, armored military vehicles. Any word with the prefix anti goes against something else. Therefore, antitank measures and equipment are designed to defend against attack by tanks. An antitank gun fires at a tank, hoping to hold it off. An antitank barrier is designed to hold back a tank and must be extremely strong. This word is a lot like antiaircraft and antisubmarine, which describe defenses against aircraft and submarines.
