单词 P
释义 P
the sixteenth letter of the alphabet in English and other modern languages, was the fifteenth in the ancient Roman alphabet, corresponding in position and value to the Greek Pi, Π, Π, earlier {egpi1}, {egpi2}, originally written from right to left {egpi3}, and identical with the Phenician and general Semitic Pe, forms of which were 𐤐, {egpi3}. During its whole known history the letter has represented the same consonantal sound, viz. the labial tenuis, or lip unvoiced stop, to which the corresponding sonant or voiced stop is B, and the nasal, M. In English, the simple p has always this sound; but it is sometimes silent, as initially in the combinations pn-, ps-, pt- (representing Greek πν-, ψ-, πτ-), and medially between m and another consonant, as in Hampstead, Hampton, Sampson, Thompson, Dempster, Tompkins, where it is not etymological, but has the function of indicating for the preceding m the short and semi-sonant value which m naturally has before pronounced p: cf. Simpson, crimson |ˈsɪmsən, ˈkrɪmz(ə)n|, with wimple, wimble. In words from Latin, such as exempt, tempt, peremptory, assumpsit, consumptive, redemption, and some others, as Humpty-Dumpty, where the p is (so far as English is concerned) etymological or consciously derivational, there is generally in careful utterance an intention to pronounce it, resulting in an incomplete p, which we indicate thus |tɛm(p)t|, |riːˈdɛm(p)ʃən|; but, in rapid or careless utterance, the p disappears, just as in Ham(p)ton, Thom(p)son.
The digraph ph, ph, is used, in continuation of Latin usage, to transliterate the Greek letter ϕ, ϕ, the phonetic value of which is now identical with that of F. The words beginning with ph have thus the same relation to the P words proper that those in ch have to the C words; that is, they constitute an alien group, which, only for alphabetical convenience, occupy a place in the midst of the P words proper, between pe-, and pi-.
Original P in Germanic or Teutonic represents an Indo-European B. But, initially, B was of rare occurrence in Indo-European, and it is not certain that any of the words in which it so occurred were retained in Teutonic, where initial P was consequently very rare. Of the OE. words in P, a few were apparently Common West Germanic, a very few, Common Teutonic; of many of the remainder the origin is quite obscure, but the majority were manifestly adoptions within the historical period from other languages, chiefly from Latin. Notwithstanding these extraneous additions, P remained the smallest initial letter (the exotic K, Q, not being counted) in the Old English or Anglo-Saxon vocabulary, occupying less than half the space of I, and little more than two-thirds of that of Y. Its relation to the other mutes, C (= K) and T, and to its own sonant B, is seen by the pages which these occupy in Toller's edition of Bosworth's Anglo-Saxon Dictionary, which are C 50, T 64, B 78, P 8½ pages. P might be expected to comprise a correspondingly small part of the modern English vocabulary; on the contrary, it is actually the third largest initial, being surpassed only by S and C, with which it forms a triad of gigantic letters, which include nearly a third of all the words in the dictionary. This result is mainly owing to the vast accessions from Greek, Latin, and the modern Romanic languages (chiefly, of course, from French), and especially to the enormous number of words formed with the Latin prefixes per-, post-, pre-, pro-, and the Greek para-, peri-, pro-, along with the PH group already referred to. But, besides these, P has received great additions, not only in later times from Oriental, African, American, and other remote languages, but, during the Middle English and Modern periods alike, of a multitude of common, familiar, or lower-class words from sources which cannot be traced, often apparently from fresh word-formation. P thus presents probably a greater number of unsolved etymological problems than any other letter.

1. The letter |piː|. Plural Ps, P's, p's |piːz|.
attrib. as p-language, a language which preserves original p, or substitutes it for other sounds, as Greek which has πεντέ against L. quinque, or Welsh which has pedwar against OIr. cether, from *qetwer, L. quatuor. Used spec. to designate one of the two main groups of languages which developed from Common Celtic, so called because its distinctive phonological features include the development of IE. *qu to p, as P-Celtic, P-division, P-group, etc.; P-Celt, a speaker of P-Celtic.

2. Used, like the other letters, to indicate serial order, as in the ‘signatures’ of the sheets of a book, the Batteries of the Horse Artillery, etc.
3. P and Q.
a. to be P and Q (Pee and Kew).
According to Bound Provincialisms as quoted in Eng. Dial. Dict., this was used in 1876 in Shropsh. and Herefordsh. in the sense ‘to be of prime quality’.
1612Rowlands Knave of Harts (Hunterian Cl.) 20 Bring in a quart of Maligo, right true: And looke, you Rogue, that it be Pee and Kew.
b. to mind one's P's and Q's (peas and cues), to be careful or particular as to one's words or behaviour. So to be on (in) one's P's and Q's.
1779H. Cowley Who's the Dupe? i. i, You must mind your P's and Q's with him, I can tell you.1800W. B. Rhodes Bomb. Fur. iv. 30 My sword I well can use So mind your P's and Q's.a1825Forby Voc. E.

c. one's P's and Q's, put for ‘one's letters’.
1820Combe Consol. i. 30 And I full five-and-twenty year Have always been school-master here; And almost all you know and see, Have learn'd their Ps and Qs from me.[Note. As to the origin of these nothing has been ascertained. An obvious suggestion is that b. (for which the evidence does not go far back) refers to the difficulty which a child beginning to read has in distinguishing the tailed letters p and q; others have conjectured some cryptic reference to the words peculiar, or particular. There is no necessary connexion between b. and a., which belongs to an earlier date. In a still earlier passage from Dekker 1602, ‘Now thou art in thy pee and cue’, pee means the coat so called (see pee n.), and cue app. either queue, or cue n.2 sense 3 or 4; but there may have been a punning allusion to the expressions here considered, if they were then current.] 4. P.Z. exercise (R.N.), an exercise at sea.
1905Trans. Inst. Naval Archit. XLVII. ii. 305 The P.Z. exercises have been so conducted as to be deceiving.1916‘Taffrail’ Pincher Martin viii. 140 Gunnery, gunnery, toujours gunnery—unless it was torpedo-running, steam tactics, or P.Z.

By definition, the perceived noise level of sound ‘X’ (in PNdb) is the sound pressure level in db re 0·0002 µbar of the 910– 1090 cps band of random noise that is judged by an average listener to be acceptable (or, inversely, as unacceptable) as sound ‘X’, under specified conditions of listening and testing.1966Science 18 Mar. 1346/3 As a practical matter, the loudness level, in phons, and the perceived noise level, in PNdb's, of a sound are usually calculated from acoustical measures of the sound rather than found by subjective judgement tests.1971New Scientist 18 Mar. 604/1 In calculating the NNI for any given point, a number of standard flight paths are assumed and the PNdB level for each type of aircraft moving along each possible flight path is then calculated, together with the number of aircraft movements.
