Lexical Investigations: Fiat

fiat, genesisThe origin of the word fiat in English is connected to the origin of the world itself. Taken from the Latin meaning “let it be done,” this word appears in the Latin translation of Genesis, the first book of the bible, when God proclaimed “let there be light” (fiat lux). As a result, many early uses of fiat were biblical allusions, as in John Donne’s 1597 poem The Storm. In it he writes that there will be darkness unless “God say/Another Fiat.”

It was not until the 1630s that English speakers started using fiat to describe an “authoritative decree,” often issued by royalty or clergy—two groups that depended on divine right for their power. By the turn of the 19th century, English speakers applied fiat’s meaning to less-than-Godly legal manners. The phrase “fiat in bankruptcy” gained popularity at this time. Later that century, the concept of “fiat money,” or currency that has no intrinsic value, but that the government gives a value to by declaring it legal tender, took its place in English-speaking minds.

The name of Fiat, the Italian car company, is an acronym, not only a nod to this powerful word. Its name originally stood for Fabbrica Italiana Automobili Torino, meaning loosely “Italian automobile factory of Turin,” the region in which the country was founded.

According to the Google Ngram Viewer, the word “fiat” peaked in usage in the 1840s, possibly due to the political upheaval of the revolutions of 1848.

    Really? some of you guys would rather search for spelling errors than actually enjoy the article? you guys have to remember that dictionary.com isnt an actualy dictionary but a group of nice people who spend their time bringing us these nice articles. and god forbid them from being human and putting in a spelling error i mean seriously there only human. so please remember that next time you grammar nazi’s go looking for errors on dictionary.com.

      If this was a site like, say Huffington Post, I would agree 100% with you. By choosing the URL “dictionary.com,” this site has set itself up as an authority of the English language. As such, any error – even very minor ones – are inexcusable. Each entry should be proofread by at least five people before being posted.

    Some of you people are being a bit ridiculous. The fact that minor errors that do not change the purpose of the article are present is not “egregious”. Did a dictionary write this article? No, a human being who is not incapable of making mistakes did. Get off your high horses please, for the sake of your own well being.

    If you are a non-believer, you can argue that the bible has many illusions.

    I appreciate having learned the term, “fiat money”. This term describes the currency of the United States of America. There may be some illusion regarding the value of this currency.

  18. Rob -  August 15, 2013 - 8:36 am

    Yes, it must say “the city in which the company was founded”, as the company was founded in the city of Turin (Torino, in Italian)

  19. Emperator -  August 15, 2013 - 8:18 am

    Illusions or allusions?

  20. Tommaso -  August 15, 2013 - 7:33 am

    It should be “the TOWN in which the COMPANY was founded”…

  21. ECM -  August 15, 2013 - 6:52 am

    In the first paragraph, you say, “As a result, many early uses of fiat were biblical illusions”, but it looks like what you meant was “allusions”. Please clarify for your readers the difference between these two words, which can so easily be confused with each other.

  23. Jamie -  August 15, 2013 - 6:00 am

    Shouldn’t biblical “illusions” be “allusions”? Do I get to write this column now?

  24. Moonmaiden -  August 15, 2013 - 5:03 am

    Should that read ‘biblical allusions’ in the first paragraph? In any case I love this site :-)

  25. ram singh -  August 15, 2013 - 4:41 am

    I owned one of these cars FIAT 124 in the seventy’s. Was cheap on gas, fast and reliable. I also travelled to TURIN but never knew the origin of the word. Of course, there was no internet then to refer to.

    In the first paragraph, a sentence reads: As a result, many early uses of fiat were biblical illusions, as in John Donne’s 1597 poem The Storm.”

    Do you not mean “biblical allusions?” This seems like a bad error to me.

  29. JT -  August 14, 2013 - 9:37 pm

    The first paragraph reads, “As a result, many early uses of fiat were biblical illusions…” Shouldn’t this say ALLUSIONS instead of ILLUSIONS? You would think a dictionary website could know the difference between 2 words, that’s a 9th grade skill at the highest…

  30. Interesting -  August 14, 2013 - 9:03 pm

    If I may…

    I’m not entirely certain, but would it be biblical “allusions”?

  31. Jory Piccinino -  August 14, 2013 - 6:39 pm

    “As a result, many early uses of fiat were biblical illusions”–

    I think the writer here, ironically of Dictionary.com, means to say “allusions,” as in something “alluded to,” a reference made.

  32. Nick Burton -  August 14, 2013 - 5:48 pm

    Ya it should be The company was founded.. and p.s. The NBA is crooked they only have love for money and not the sport. they only pick the bandwagon teams to win for the money. They know that the toads will pay 100$ for a piecce of shit Lakers jersey.. Screw the nba

  33. Hebeestie Wallopman -  August 14, 2013 - 2:30 pm

    Passer by, maybe Fiat founded a country to contain their company.

  34. PaperFace -  August 14, 2013 - 2:25 pm

    Thoughts :
    “Meaning LOOSELY” – Don’t lean so heavily on this translation, as the author is stressing here!

    “The region in which…” – It is entirely possible that the fabrication efforts were from many areas in the REGION? Not just Turin?

    @Passer By – Good catch. Most likely…

  35. Yorkshirelad -  August 14, 2013 - 1:56 pm

    A lexicographic article and you use the phrase” . . . uses of fiat were biblical illusions . . .” – surely you mean “allusions”. Please consult a dictionary in future.

  36. Bemused1 -  August 14, 2013 - 1:19 pm

    I believe the word the writer was seeking was allusions, not illusions. Writers and speakers were making allusions to the Bible, though they may have had illusions at the same time.

  38. Lori -  August 14, 2013 - 10:12 am

    Many of the first uses were Biblical *allusions*.

  39. DAVE HARDING -  August 14, 2013 - 9:08 am

    I was told it meant “Fix it again tomorrow!”

    • Michele -  July 6, 2016 - 6:36 pm

      “FIAT” – ‘Fix it again Tony” :)

      PS Chrysler-Fiat of NA…. ‘Fix it again Tony’ ‘is now’ more of a fact than ever.

  40. bookbeater -  August 14, 2013 - 8:57 am

    ok i’ll point out the poor use of illusions tsk tsk

  41. Michael Poplawski -  August 14, 2013 - 8:29 am

    “Biblical illusions” for the proofreading hat trick.

    I think you mean “biblical allusions”.

  42. svenjamin -  August 14, 2013 - 8:09 am

    All this time I thought FIAT stood for “Fix It Again Tony”, go figure!

  43. KUNTURMARKA -  August 14, 2013 - 6:38 am

    This short article has three egregious errors that are unforgivable in a website devoted to knowledge in general and to the origins and meanings of words in particular:

    1. “As a result, many early uses of fiat were biblical illusions…”. This sentence should read “As a result, many early uses of fiat were biblical ALLUSION…”. From dictionary.com:

    Allusion (n). A passing or casual reference; an incidental mention of something, either directly or by implication; the act or practice of making a casual or indirect reference to something; the act of alluding.

    2. “…the region in which the country was founded…”. In fact, Torino (Turin), as has been mentioned in an earlier comment, is a PROVINCE, not a region, of which the capital is the CITY of Torino.

    3. The sentence above, as another commenter noted, should end “…in which the COMPANY (or MANUFACTURER) was founded…”.

    Please correct these mistakes.

  44. Gabrielle -  August 14, 2013 - 6:22 am

    Same thing with “illusion”…should be “allusion”. !!

  45. Whatever -  August 14, 2013 - 5:00 am

    Biblical “illusions”? I think that should be “allusions”.

  46. Visitor -  August 14, 2013 - 4:38 am

    Biblical allusions, perhaps?

  47. Another Passer By -  August 13, 2013 - 10:51 pm

    “As a result, many early uses of fiat were biblical illusions…”

    Shouldn’t that be allusions?

  48. Mark -  August 13, 2013 - 6:21 pm

    I always thought FIAT stood for Fix It Again Tony.

  49. ffeff -  August 13, 2013 - 4:24 pm

    “As a result, many early uses of fiat were biblical illusions…”
    How shameful of a DICTIONARY to make this kind of mistake. Allusions is the word that is wanted. Yikes.

  50. Michael Chesworth -  August 13, 2013 - 3:22 pm

    Oh, I don’t think Donne “yused” fiat. That’s what comes of typing with 10 thumbs!

  51. Michael Chesworth -  August 13, 2013 - 3:21 pm

    The first paragraph talks about Biblical illusions. The context of Donne’s reference is to the yuse of Fiat in Genesis.

    In that case, should that not be “allusions”?

  52. Clark -  August 13, 2013 - 2:13 pm

    In the second sentence of the second paragraph, “Manners” should be “matters”.

  53. Clark -  August 13, 2013 - 2:09 pm

    In the third sentence of the first paragraph, the word, “illusions” should be “allusions”.

  54. JCAV -  August 13, 2013 - 1:24 pm

    I thought it stood for Fix It Again Tony…

  55. JCAV -  August 13, 2013 - 1:23 pm

  56. ko -  August 13, 2013 - 12:28 pm

    not illusion, but allusion. What kind of dictionary site are you?

  57. Archon -  August 13, 2013 - 9:49 am

    Many early uses of the word FIAT, would be Biblical “Allusions”!

  58. Passer By -  August 13, 2013 - 5:53 am

    It reads “the region in which the country was founded.”

    shouldn’t that be “the region in which the COMPANY was founded.” ?

  59. Gianfranco -  August 13, 2013 - 2:27 am

    Turin is not a region but a city of over one million inhabitants. The region is called Piemonte, cognate with English Piedmont – both meaning “at the foot of the mountains”.
