The Origin of Cantankerous Is Mysterious

A person described as cantankerous may find it more difficult than most to turn that frown upside down, while a cantankerous mule/jalopy/etc. is difficult to deal with—it may not turn in your desired direction. It’s been speculated that cantankerous is a product of the obsolete word contack, meaning “contention,” under the influence of a pair of “difficult” words still in use: rancorous and cankerous. Rancorous brings the anger and “bitter deep-seated ill will” (as rancor can be understood to mean), and cankerous brings the perhaps understandable foul mood: a cankerous person suffers from painful sores—that is, cankers.
