    徐清枫同学的blog里看到他的一篇文章,根据他的推理,PPT并不是PowerPoint的缩写,而是有可能是PowerPoint Presentation的缩写,我很喜欢他的推测。现在PPT好像已经成了一个约定成俗的语类了,但是到底PPT是怎么来的,它是不是就是PowerPoint的缩写呢?本着求证的态度,找了很多资料,可惜都没有答案。最后决定给Robert Gaskins写封信询问一下,他是PowerPoint最初的编写者,应该最有发言权。老人家非常热情,回了一封非常详细的解释,大概总结一下意思如下:

    1.PPT并不是PowerPoint的缩写,而是简称。(这个要怪我的英语水平不好,在Gaskin看来, acronym(缩写)和abbreviation(简称)是不一样)。
    2.最初他编写PowerPoint的时候是给苹果系统写的,但当时他们已经预见到了微软将来可能一统江湖,所以在文件命名的时候还是遵循了微软的规则,就是后缀名不能超过3个字母,文件名不能超过8个字母。
    3.在起名字的时候,很自然的就把PowerPoint的前中后三个字母提取出来成为后缀名,接着又衍生出一个系列如PPS(PowerPoint show)等。
    4.在新的微软系统中,已经没有了后缀名只能3个字母的限制,所以2007版的就有4个字母的后缀名了,如PPTX,这个X是基于XML而来的。

    虽然最后的答案还是没有出人意料,但总算也了解到了事情的来龙去脉,是一份不错的收获。将Gaskin的原信附上,大家一起学习吧。

    Dear Eddie Liu,

      Thanks for writing about the meaning of "PPT".

      "PPT" is not properly an acronym for PowerPoint, because

                "Acronyms ... are abbreviations that are formed using the
           initial components in a phrase or name. These components may
           be individual letters (as in CEO) or parts of words (as in Benelux or
           Delmarva)."
           --http://en.wikipedia.org/wiki/Acronym

     An acronym can be formed by taking the initial letters of multiple
    words, sometimes only the important words, for example

           BBC: British Broadcasting Corporation
           CNN: Cable News Network
           USA: United States of America

    (there are other types as well).

      So an acronym is a special kind of abbreviation formed from initial
    components such as letters, and "PPT" was not made up that way.  (All
    acronyms are abbreviations, but most abbreviations are not acronyms.)

      The need for the abbreviation "PPT" came about in this way.  In
    Microsoft's early MS-DOS system and later in Windows, every filename
    ended in a dot (".") followed by a short "file type".  (See
    http://en.wikipedia.org/wiki/Windows_file_types.)  In MS-DOS in the
    1970s, and then in early versions of Windows built on MS-DOS, the file
    type had to be only 3 letters.  A filename had a maximum of 8 letters,
    then the dot, then a 3-letter file type, so this naming format was
    called "8+3".  When PowerPoint was invented, we had to decide on a
    3-letter abbreviation to identify its files to the operating system.
    Even though PowerPoint was developed first for Macintosh, we knew from
    the very beginning that the most important target would be Microsoft
    Windows, so we planned for it all along.

      In English, abbreviations of single words are often formed by
    taking the first letter of the word and the last letter of the word,
    adding between them the most important letters from the middle to show
    what the word sounds like.  For example,

      MR:  mister
      JR:   junior
      DR:  doctor
      REVD:  reverend
      MGMT: management

      We made "PPT" as an abbreviation for PowerPoint, by taking the
    first 'P" and the last "T", adding between them the middle "P":
    PowerPoinT.  This was natural, because in English "power" is a common
    word all by itself, and "point" is a common word all by itself, so
    people understand "PowerPoint" as a combination of the two
    words--further indicated by the fact that we capitalized both "P"s.

      "PPT" was a natural English abbreviation for the word "PowerPoint"
    and it was the right length (3 letters) to be an MS-DOS file type.

      As to the others, any computer program deals with many types of
    files.  Each file type required a different 3-letter abbreviation.  We
    made up other file types by making them similar to "PPT"--for
    instance, "PPS" for "PowerPoint Show".  Since they all start with "P",
    you can sort a list of files by their file types and find all the ones
    for the PowerPoint program sorted together.

      Much later (as you say, starting with PowerPoint 2007), Microsoft
    introduced new files formats, the XML-based formats.  By this time,
    file types could be longer than 3 characters because the foundations
    of Windows had been entirely rewritten.  For example, in early
    versions of Windows, HTML files could only have the file type "HTM"
    ("index.htm"), but now you often see HTML files of file type "HTML"
    "index.html").

      Microsoft used this freedom to make 4-letter file types for the new
    formats, by using the old file types ("PPT", "PPS") and adding an "X"
    (from "XML"), resulting in new file types "PPTX", "PPSX" and so forth.
     This way you can look at a listing of one of the new files and see
    instantly that it is, for example, "the XML revision of a PPT file".

      I hope this explains how "PPT" came about.

    Best regards,

    Robert Gaskins

  • 老外果然认真呀 看来大乘起信老师也得偶尔回答点新手问题
  • PPT。我以为是ms的ppt呢
  • 老外的认真和执着令人敬佩,博主的求真同样令人敬佩
  • 关于Acronym和Abbreviation的区别,人家R.B.老头儿已经解释的很明白了。
    Acronym 首先形式上肯定是一个词组中取各词首字母形成的(金山词霸解释:取首字母的缩写),这是判断是否是此类词汇的关键标准。至于2楼说的能不能作为单独词发音这个标准,显然不能作为一般标准。比如像很多公司的名字,如IBM,ABB这样的,又比如像英文书信中常用的ASAP,肯定不是个可以单独发音的词汇,但毫无疑问它们是Acronym。
    Abbreviation,顾名思义,就是缩写,其范围是包含Acronym的。形式多样,比如,大家嫌Abbreviation这个词太长,经常写成abbr.,这就算缩写。
    另外,赞楼主的学习精神,赞R.B.老头儿的认真劲儿,学习。
  • 老外做事超细致
  • 以前学英语的时候,强调acronym是可发音的,比如UNICEF和AIDS,在取了首字母之后,单独成为一个词而发音,ppt显然不能作为一个单独词发音,所以我会把它归于abbreviation。

    这还是大学课上老师说的(偶是英语专业)。不知道有没有道理。
  • 原来PPT三个字母是这个含义 不过PPT怎么会是为苹果设计的呢?这个没想明白,哈哈。受教了
