jury-rig [n. v. JOO-ree rig]

----------------------------------------------------------------------


A jury-rig is a makeshift assembly that's just temporary, an emergency
measure improvised out of available materials, and to make one is to
jury-rig. Example: "The injured hiker jury-rigged a splint out of
sticks and twine."

The most likely origin is from the Old French ajuri (help), from the
Latin adiutare (aid). In this context, the word "jury" was originally
a nautical term meaning "temporary," as in a "jury sail." This is
distinct from the other meaning of "jury" (a group of persons sworn to
judge and give a verdict), which comes from Latin iurare (to swear),
from ius (law).
