Pronunciation and etymology

The present word has alternate spellings (kludge and kluge) and pronunciations (ˈklʌdʒ and ˈkluːdʒ, rhyming with fudge and stooge respectively), and several proposed etymologies.

The word kludge is a synthesis of the words "fudge" and "kluge" and forms a linguistic mirror of its meaning by being itself: "an ill-assorted collection of poorly-matching parts, forming a distressing whole." Kludge has absorbed the colloquial meaning of fudge, which itself is used to swallow the cruder interjection "fuck", and hence fudge passes on an "all fucked up" sense as well. These meanings in conjunction with the makeshift sense of kluge form the constellation of allusions cast by the word kludge.

kludge (ˈkluːdʒ) Also kluge. [J. W. Granholm's jocular invention: see first quot.; cf. also bodge v., fudge v.]

'An ill-assorted collection of poorly-matching parts, forming a distressing whole' (Granholm); esp. in Computing, a machine, system, or program that has been improvised or 'bodged' together; a hastily improvised and poorly thought-out solution to a fault or 'bug'. …

The word 'kludge' is...derived from the German adjective klug, originally meaning 'smart' or 'witty'.... 'Kludge' eventually came to mean 'not so smart'.

Kluge is a German-derived surname. Among German-speakers, it is pronounced "KLOO-guh" and is derived from the German adjective klug .Those bearing it include:* Friedrich Kluge , German linguist...

 derives from klug "prudent; smart". Although the OED2 notes Granholm was "jocular", it accepts his ironic etymology from a fictional "Fink and Wiggles" for Funk & Wagnalls lexicographer.
A phone call to Phineas Burling can be revealing. Phineas Burling is the Chief calligrapher with the Fink and Wiggles Publishing Company, Inc. Fink and Wiggles are, of course, the well known publishers of the NEW MULTILINGUAL DICTIONARY. According to Burling, the word "kludge" first appeared in the English language in the early fifteen-hundreds. It was imported into the geographic region of the lowlands between King's Lynn (then Bishop's Lynn) and the Isle of Ely by Dutch settlers arriving there to reclaim tidelands of the Wash as rutabaga fields. …

The word "kludge" is, according to Burling, derived from the same root as the German "klug" (Dutch kloog, Swedish Klag, Danish Klog, Gothic Klaugen, Lettish Kladnis and Sanskrit Veklaunn), originally meaning "smart" or "witty". In the typical machinations of language in evolutionary growth, the word "Kludge" eventually came to mean "not so smart" or "pretty ridiculous". Today the leading definition given by the NEW MULTILINGUAL is, "An ill-assorted collection of poorly-matching parts, forming a distressing whole."

It is in this latter sense that "Kludge" is used by computer hardware men. Today "kludge" forms one of the most beloved words in design terminology, and it stands ready for handy application to the work of anyone who gins up 110-volt circuitry to plug into the 220 VAC source. The building of a Kludge, however, is not work for amateurs. There is a certain, indefinable, masochistic finesse that must go into true Kludge building. The professional can spot it instantly. The amateur may readily presume that "that's the way computers are".

This OED2 entry also includes the verbal kludge "to improvise with a kludge or kludges" and kludgemanship "skill in designing or applying kludges".

First, kluge "was common Navy slang in the WWII era for any piece of electronics that worked well on shore but consistently failed at sea". A 1947 article in the New York Folklore Quarterly recorded the classic shaggy dog story "'Murgatroyd the Kluge Maker' then current in the Armed Forces, in which a 'kluge' was a complex and puzzling artifact with a trivial function." When Murgatroyd enlists into the Navy, he gives "kluge maker" as his occupation. Because none of the officers knows what a kluge is, Murgatroyd ascends through the ranks, eventually becoming "kluge maker, first class". When an admiral demands that Murgatroyd build him a kluge, he constructs a strange object with springs in all directions. He then drops it over the side of the ship into the ocean, where it goes "kkluuge".

 reputation, and was "temperamental, subject to frequent breakdowns, and devilishly difficult to repair — but oh, so clever!"

The Jargon File further includes kluge around "to avoid a bug or difficult condition by inserting a kluge", kluge up "to lash together a quick hack to perform a task". After Granholm's 1962 "How to Design a Kludge" article popularized the kluge variant kludge, both were interchangeably used and confused. The Jargon File concludes:
The result of this history is a tangle. Many younger U.S. hackers pronounce the word as /klooj/ but spell it, incorrectly for its meaning and pronunciation, as 'kludge'. … British hackers mostly learned /kluhj/ orally, use it in a restricted negative sense and are at least consistent. European hackers have mostly learned the word from written American sources and tend to pronounce it /kluhj/ but use the wider American meaning! Some observers consider this mess appropriate in view of the word's meaning.


Other suggested folk etymologies or backronyms for kludge or kluge is from klumsy, lame, ugly, dumb, but good enough, or klutzy, lashup, under, going, engineering.

Recapitulation

As noted above, the term "kluge" as an overly-complicated or obscure contraption dates back at least to 1947, as evidenced by the article in the "New York Folklore Quarterly" (see ref. 5), but the term must have been in use long before that for the story to have any sense. The following purports to be a summary of the original article that is somewhat more complete than the one quoted above:

On being drafted into the navy, Murgatroyd gave his profession as "kluge maker".
Not wanting to seem ignorant, the clerk simply wrote this down.
Whenever Murgatroyd was asked what he was doing, he said he was making a kluge, and actually he was one of the world's best kluge makers.
Not wanting to seem ignorant, his superiors kept giving him commendations and promotions, until he reached the dizzy heights of commodore.

One day the admiral came to inspect the ship.
When Murgatroyd explained he was a kluge maker, the admiral asked him what a kluge was - the first person ever to do so.
Murgatroyd said it was hard to explain, but he would make one so the admiral could see what it was.
After a couple of days, he returned with a complex object.

"Interesting," said the admiral, "but what does it do?"

In reply, Murgatroyd dropped it over the side of the ship. As the thing sank, it went "kluge".http://our-local.co.uk/index.php?topic=23170.5;wap2


A reasonable hypothesis for the origin of the term dates back to 1907, "when John Brandtjen convinced two young machinists from Oslo, Norway named Abel and Eneval Kluge to service and install presses for his fledgling printing equipment firm" (see external link, history of the Kluge Platen Press). In 1919, the brothers invented an automatic feeder for printing presses which, by 1929, allowed Brandtjen & Kluge to move into a 3-story building in St. Paul, MN. The Kluge brothers continued to innovate, and the company still exists as of 2011.

While the automatic feeder was a success, unverified sources claim that it developed a reputation for being temperamental, prone to breakdowns, and difficult to repair. Given that the feeder bore the Kluge name, it seems reasonable that it became a byword for overly-complex mechanical contraptions. The Free Online Dictionary of Computing claims that the kluge "was used in connection with computers as far back as the mid-1950s and, at that time, was used exclusively of *hardware* kluges".http://foldoc.org/kluge The fact that it was originally applied only to hardware again points back to the paper feeder as the original source of the term. FOLDOC goes on to say, "TMRC and the MIT hacker culture of the early 1960s seems to have developed in a milieu that remembered and still used some WWII military slang (see also foobar). It seems likely that "kluge" came to MIT via alumni of the many military electronics projects run in Cambridge during the war (many in MIT's venerable Building 20, which housed TMRC until the building was demolished in 1999)." This would explain the terms introduction into the software community.

This explanation would then point to the source of the term as a Norwegian surname, with no connection to German.

The term "kludge" would then seem to have separate origins, possibly in Britain. The terms tended to merge because of their similar pronunciations and meanings. However, "kluge" seems to have the sense of overly complicated, while "kludge" has only the sense of poorly done.

In aerospace engineering

In aerospace design a kluge was a temporary design using separate commonly available components that were not flight worthy to proof the design and enable concurrent software development while the integrated components were developed and manufactured. The term was in common enough use to appear in a fictional movie about the US space program.

Note that a hack might be a kludge, but that 'hack' could be, at least in computing, ironic praise, for a quick fix solution to a frustrating problem.

As a consequence, they are sometimes ironically praised.

It's not that we have fundamentally human thoughts and feelings despite the kludgy design of the brain as molded by the twists and turns of evolutionary history. Rather, we have them precisely because of that history.
