Etymology
Origin of jar1
First recorded in 1585–95; Middle English jarre “liquid measure smaller than a barrel,” possibly from Old French jarre, from Spanish or Portuguese jarra, jarro “a jar, pitcher,” or from Medieval Latin jarra, from Old Provençal jarra, from Arabic jarrah “earthen water vessel”

Origin of jar3
Explanation
A jar is a smooth-sided, round container that's often made of glass. Jars are useful for storing food, from rice to tea bags to cookies. A wide-mouth jar made of pottery might hold Oreos, and a small, short jar could contain homemade jam. When you put something in a jar, you jar it. Another way to use the verb version of jar is to mean "shock painfully or unpleasantly:" "Every bump we drove over in the old Jeep would jar my whole body." The jar that's a container probably stems from the Middle French jarre, "liquid measure."
