'''Chad''' refers to fragments sometimes created when [[Hole punch|hole]]s are made in a paper, card or similar synthetic materials, such as computer [[punched tape]] or [[punched card]]s. The word "chad" has been used both as a [[mass noun]] (as in "a pile of chad") and as a [[countable noun]] (pluralizing as in "many chads").

== Etymology ==
The origin of the term chad is uncertain. Patent documents from the 1930s and 1940s show the word "chad", often in reference to punched tape used in [[teleprinter|telegraphy]].  These patents sometimes include synonyms such as "[[chaff]]" and "[[chip (waste)|chip]]s".  A patent filing in 1930 included a "receptacle or ''[[chad box]]'' ... to receive the chips cut from the edge of the tape."<ref>Howard L. Krum, Coupon Printer, [https://patents.google.com/patent/US1884755 U.S. Patent 1,884,755], filed Oct. 16, 1930, issued Oct. 25, 1932.</ref> A 1938 patent filing included a "chaff or ''chad chute''" to collect the waste fragments.<ref>Albert H. Reiber, 
Telegraph Transmitter, [https://patents.google.com/patent/US2213475 U.S. Patent 2,213,475], filed July 18, 1938, issued Sept. 3, 1940.</ref> Both patents were assigned to [[Teletype Corporation]].

The plural ''chads'' is attested from about 1939, along with ''chadless'', meaning "without [loose] chad".  Clear definitions for both terms are offered by Walter Bacon in a patent application filed in 1940 assigned to [[Bell Telephone Laboratories]]:  "... In making these perforations, the perforator cuts small round pieces of paper, known in the art as ''chads'', out of the tape.  These ''chads'' are objectionable ... ''Chadless'' tape is prepared by feeding blank tape through a device which will not punch a complete circle in the tape but, instead, will only cut approximately three-quarters of the circumference of a circle ... thereby leaving a movable, or hinged, lid of paper in the tape."<ref>Walter M. Bacon, Tape Splicer, [https://patents.google.com/patent/US2246655 U.S. Patent 2,246,655], filed Feb. 20, 1940, issued June 24, 1941.</ref>

In the ''[[New Hacker's Dictionary]]'', two unattributed and likely humorous{{Citation needed|date=February 2024}} derivations for "chad" are offered, a [[back-formation]] from a personal name "Chadless" and an [[acronym]] for "Card Hole Aggregate Debris".<ref>[[Eric S. Raymond]], Chad, [https://books.google.com/books?id=g80P_4v4QbIC&pg=PA108 The New Hacker's Dictionary], Third Ed., 1996; page 108.</ref>  Other etymologies claim derivation from the [[Scotland|Scottish]] name for river gravel, ''chad'', or the [[United Kingdom|British]] slang for [[louse]], ''chat''.{{Citation needed|date=July 2011}}

=={{anchor|Partial}}Partially punched chad==
When a chad is not fully detached,  it is described by various terms corresponding to the level of modification from the unpunched state. The distinctions are of importance in counting cards used in voting. The following terms are sometimes used when describing a four-cornered chad:

*Hanging chads are attached to the ballot at only one corner.
*Swinging chads are attached to the ballot at two corners.
*Tri-chads are attached to the ballot at three corners.
*Dimpled chads are attached to the ballot at all four corners, but bear an indentation indicating the voter may have intended to mark the ballot.<ref>{{cite web|url=https://www2.norc.org/fl/method3.asp|title=Methodology : Coding Process|publisher=Florida Ballots Project|access-date=2009-05-23|url-status=dead|archive-url=https://web.archive.org/web/20081120132047/http://www2.norc.org/fl/method3.asp|archive-date=2008-11-20}}</ref> (Sometimes "pregnant" is used to indicate a greater mark than "dimpled".)<!-- Unsourced 'pregnant' description -->

In the [[2000 United States presidential election in Florida]], many [[List of counties in Florida|of the state's counties]] used [[Voting machine#Punched card voting|Votomatic-style]] punched card ballots where incompletely punched holes resulted in partially punched chads: either a "hanging chad", where one or more corners were still attached, or a "fat chad" or "pregnant chad", where all corners were still attached, but an indentation appears to have been made. These votes were not counted by the tabulating machines.<ref>{{cite web |url=http://archives.cnn.com/2000/ALLPOLITICS/stories/12/13/got.here/index.html |title=How we got here: A timeline of the Florida recount |date=December 13, 2000 |publisher=[[CNN]] |access-date=2009-05-23 |url-status=dead |archive-url=https://web.archive.org/web/20090611112919/http://archives.cnn.com/2000/ALLPOLITICS/stories/12/13/got.here/index.html |archive-date=2009-06-11 }}</ref><ref>{{cite web|url=http://archives.cnn.com/2000/ALLPOLITICS/stories/11/16/recount.chads/|title='Hanging chads' often viewed by courts as sign of voter intent|last=Jackson|first=Brooks|date=November 16, 2000|publisher=CNN|access-date=2009-05-23|url-status=dead|archive-url=https://web.archive.org/web/20090611112914/http://archives.cnn.com/2000/ALLPOLITICS/stories/11/16/recount.chads/|archive-date=June 11, 2009}}</ref> The aftermath of the controversy (''[[Bush v.
