Colonel – Colonel is originally Italian, a colonel being the commander of a military column or in Italian colonna. The French adopted the military rank, and in so doing switched the L for R (L/R switches are a common pronunciation shift). English adopted the French word, with an R spelling coronell in the mid-16th century. Starting in the late-16th century, translations of Italian military treatises started using the etymologically correct L spelling, and by the mid-17th century, colonel was the accepted English spelling. But the R pronunciation was firmly established and did not change.
Cold Turkey -This phrase meaning without preparation dates to 1910. The use in relation to withdrawal from an addictive substance (originally heroin) dates to around 1922.

The military use of jody call and the sense of jody meaning a civilian of draft age date to World War II and were introduced to the U.S. Army by African-American soldiers. Jody is a clipping of the name of Joe the Grinder, a slightly older character in jazz and blues mythology. Joe the Grinder is the name of mythical ladies man in blues tunes who seduces the wives and sweethearts of prisoners and soldiers. He’s also known as Joe De Grinder and Joe D. Grinder.

Jerk – is an old word, dating to the sixteenth century. The word echoes the sound made by a short, sharp movement. The word is unremarkable, except that it has several modern, slang usages that are interesting. A soda jerk is someone who makes a living by jerking, or pulling, sodas at a lunch counter, the name coming from the jerking motion required to open a tap. A jerkwater train was originally a small locomotive that serviced branch lines. Its small boiler requiring frequent filling by train crews which would have to dismount, form a bucket brigade, and jerk water from a river to feed the steam engine. The term dates to the 1870s and is American in origin. The term jerkwater town eventually came to mean any rustic or backwards town, along a train line or not. Finally, the most common usage of jerk, meaning a fool or inept person, probably derives from jerkwater. A jerk being a resident of a jerkwater town. This usage dates to the 1930s.
