Of course it is :) It's nice-nicer-nicest. And remember-there's no such thing as a real word.. If a word is used and people understand it, then it is just as real â¦ as any word in any dictionary, or any word approved by your English teacher!
In British English, the term drive shaft is restricted to a transverse shaft that transmits power to the wheels, especially the front wheels. A drive shaft connecting the gearbox to a rear differential is called a propeller shaft, or prop-shaft. A prop-shaft assembly consists of a propeller shaft, a slip joint and one or more universal joints.
A drive shaft connecting a rear differential to a rear wheel may be called a half-shaft. The name derives from the fact that two such shafts are required to form one rear axle. Early automobiles often used chain drive or belt drive mechanisms rather than a drive shaft.
