- partial fraction — one of the fractions into which a given fraction can be resolved, the sum of such simpler fractions being equal to the given fraction: Partial fractions of 5/(x2−x) are 5/(x−1) and −5/x.
- partial function — A function which is not defined for all arguments of its input type. E.g. f(x) = 1/x if x /= 0. The opposite of a total function. In denotational semantics, a partial function f : D -> C may be represented as a total function ft : D' -> lift(C) where D' is a superset of D and ft x = f x if x in D ft x = bottom otherwise where lift(C) = C U bottom. Bottom (LaTeX \perp) denotes "undefined".
- pascal's limacon — limaçon.
- pattern matching — 1. A function is defined to take arguments of a particular type, form or value. When applying the function to its actual arguments it is necessary to match the type, form or value of the actual arguments against the formal arguments in some definition. For example, the function length [] = 0 length (x:xs) = 1 + length xs uses pattern matching in its argument to distinguish a null list from a non-null one. There are well known algorithm for translating pattern matching into conditional expressions such as "if" or "case". E.g. the above function could be transformed to 2. Descriptive of a type of language or utility such as awk or Perl which is suited to searching for strings or patterns in input data, usually using some kind of regular expression.
- pattern practice — (in foreign-language learning) a technique for practicing a linguistic structure in which students repeat a sentence or other structure, each time substituting a new element, such as a new verb, as directed by the teacher, or transforming the original structure, as in changing a statement to a question.
- pavillon chinois — crescent (def 6).
- peace campaigner — someone who campaigns for peace or an end to conflict
- peace initiative — the first or opening move in negotiating an end to conflict or negotiating peace
- peano arithmetic — (mathematics) Giuseppe Peano's system for representing natural numbers inductively using only two symbols, "0" (zero) and "S" (successor). This system could be expressed as a recursive data type with the following Haskell definition: data Peano = Zero | Succ Peano The number three, usually written "SSS0", would be Succ (Succ (Succ Zero)). Addition of Peano numbers can be expressed as a simple syntactic transformation: plus Zero n = n plus (Succ m) n = Succ (plus m n) (1995-03-28)
- pectoralis minor — the smaller of the two large chest muscles that assist in movements of the shoulder and upper arm
- pelagic division — the biogeographic realm or zone that comprises the open seas and oceans, including water of all depths.

- pencil and paper — An archaic information storage and transmission device that works by depositing smears of graphite on bleached wood pulp. More recent developments in paper-based technology include improved "write-once" update devices which use tiny rolling heads similar to mouse balls to deposit coloured pigment. All these devices require an operator skilled at so-called "handwriting" technique. These technologies are ubiquitous outside hackerdom, but nearly forgotten inside it. Most hackers had terrible handwriting to begin with, and years of keyboarding tend to have encouraged it to degrade further. Perhaps for this reason, hackers deprecate pencil-and-paper technology and often resist using it in any but the most trivial contexts.
