List of acronyms and initialisms: P

From Wikipedia, the free encyclopedia

You have new messages (last change).

This list contains acronyms, initialisms, and pseudo-blends that begin with the letter P.

For the purposes of this list:

  • acronym = an abbreviation pronounced as a series of constituent letters, e.g., SARS = severe acute respiratory syndrome
  • initialism = an abbreviation pronounced wholly or partly using the names of its constituent letters, e.g., CD = compact disc
  • pseudo-blend = an abbreviation whose extra or omitted letters means that it cannot stand as a true acronym, initialism, or portmanteau (a word formed by combining two or more words).
(a) = acronym in the example: SARS - (a) Severe acute respiratory syndrome
(i) = initialism in the example: CD - (i) Compact disc
(p) = pseudo-blend in the example: UNIFEM - (p) United Nations Development Fund for Women
(s) = symbol (none of the above, representing and pronounced as something else; for example: MHz - Megahertz)

[edit] Add new entries here or in the sub-pages

Please add your own entries, in this page or in the appropriate sub-page. Use a quasi-dictionary order, with lowercase treated the same as uppercase and ignoring non-alphanumeric characters (hyphens and such). This means that only alphanumeric characters have any significance in determining order, and that lowercase letters occupy the same ordering position as uppercase (in tie-breaker cases, list lower case first). For example: Ka appears before KA. (This differs from a strict ASCII ordering)
