Wednesday’s Word: jack

Is there any word in the English language that has more meanings than jack? Jack is a name, jack is a noun, jack is a verb. Jack is a device, a toy, a man, an animal, a cheese and an STD.

Here are a few of the meanings of this versatile, yet sometimes crude, word:

There are any number of devices called jacks which are employed to lift heavy objects. They don’t have to be mechanical like the car jack, they can be pneumatic or hydraulic.

All this and we haven’t even mentioned Jack the Cheese (Monterrey Jack), Jack the Adult Beverage (Applejack), Jack the Flag (Union Jack), Jack the Pumpkin (o’-lantern) or Jack the Highway Accident (jackknife). And maybe the strangest definition of all is this entry from the Urban Dictionary: “to pull a jack is to shit on the top of a car then sit in it.” Somebody does that!!!

The word jack has far too many definitions for me to provide sentences for each. So I’ve condensed that exercise by offering these sentences using multiple meanings of jack.

  • Because someone jacked Jack’s jack, he was unable to jack up the car to change his tire.
  • Because Jack was a jack, when he caught the jack he didn’t have enough jack to pay for the antibiotics.
  • The jackass ate all the Monterrey Jack that the lumberjack had jacked from his buddy’s lunchbox.
