What is the origin of the term "jury rig"?

Answer by  nuttree (1596)

"Jury rig" is originally a nautical term for improvised rigging, replacing a damaged mast or yards. The etymology of "jury" is not clear; it may be from Latin "adjutare" or Old French "ajurie" -- both mean help or relief -- or it may be a nautical contraction for "injury. "

Phrase "jury rigged" has been used since 1788. Adjectival use of "jury', in sense of makeshift or temporary dates from 1616, appeared in John Smith's A Description of New England. Appeared again, in similar passage, in Smith's extensive The General History of Virginia, New-England, and the Summer Isles published in 1624.
