Intermediate+ Word of the Day: crank

crank (noun, verb, adjective) /kræŋk/ LISTEN

A hand crank is the part of the machine that you can rotate with your hand.

Informally, a crank is a bad-tempered person or someone that supports bizarre causes or has strange ideas. A crank is also an arm or lever that makes a rotating part move in a machine. Therefore, to crank means ‘to rotate or move with a crank’ and ‘to start a machine using a crank.’ As an adjective, crank means ‘eccentric’ and also ‘done by an unbalanced person.’

A crank call (also known as a prank call) is a call made to annoy someone, either as a joke or intimidation, or because the caller is unbalanced. Example: “Police are investigating a spate of crank calls. The caller doesn’t say anything; he just breathes heavily on the phone.” (If there is a spate of something, it means that thing has been happening a lot.)

The related adjective cranky means ‘bad-tempered,’ so you might say, “Be careful around the boss; she’s really cranky today.” In this sense we can use it to refer to anyone, but we often use it for children: “My three-year-old is always cranky when I wake her up from a nap.” It can also mean eccentric, but it is now more common to hear crank as an adjective with that meaning. This adjectival use of crank is thought likely to be a back-formation of cranky, which first appeared in US English, but is now common in other English-speaking countries too.

Other forms

crankily (adverb), crankiness (noun)


Crank, meaning ‘a handle for turning something,’ dates back to before the year 1000. Though there is no record of crank in Old English as a stand-alone noun, cranc- appears as part of the words crancstǣf (weaver’s instrument) and crencestre (a female weaver). It can be traced back to the Proto-Germanic root krank-, and is related to a different Old English word: the verb crincan (meaning ‘to bend or yield’). While the English kept the original meaning through the Middle English cranke, Krank in German and Dutch came to mean ‘weak,’ and later ‘ill.’ The sense ‘eccentric or crazy person’ first appeared in the mid-19th century. The verb comes from the noun, and was first used in the late 16th century, meaning ‘to zig-zag.’ The meaning ‘to turn a crank’ first appeared with the invention of the automobile, in the early 20th century.
