Dn.
/diː/, U.S. /di/ I. The letter, and senses relating to the shape of the letter.
1. The fourth letter of the Roman alphabet, corresponding in position and power to the Phoenician and Hebrew Daleth, and Greek Delta, Δ, whence also its form was derived by rounding one angle of the triangular form. It represents the sonant dental mute, or point-voice stop consonant, which in English is alveolar rather than dental. The plural has been written D's, Ds, de's.The phonetic value of D in English is constant, except that in past participles the earlier full spelling -ed is retained where the pronunciation after a breath-consonant is now t, as in looked, dipped, fished, passed. The spelling -ed is now even extended to words in which Old English had t, as in wished, puffed, kissed, Old English wyscte, pyfte, cyste.Excrescent d is found in a number of words, as Mahound, sound, compound, astound, for Mahoun, soun, compoun, astoun, also the popular gownd, drownd, etc.; cf. also bound adj.1dh- is used, in the English spelling of (East) Indian words, to represent the Indian dental sonant-aspirate, in the Devanāgarī alphabet dha, also the lingual or cerebral sonant-aspirate, more exactly written ḍha. In earlier spelling by Europeans these sounds were commonly represented by simple d, and in the general rectification of this to dh, the latter has been erroneously extended to several words having simple da dental or ḍa lingual, or to words not really Indian, apparently under the notion that an oriental appearance is given to a word by spelling it with dh. Words thus erroneously spelt with dh are dhooly, dhow, dholl, dhoney, dh(o)urra, dhurrie.dj- is sometimes used to represent the Arabic letter jim, = English j /dʒ/, in Arabic, Turkish, or Berber words, which have come to us through a French channel, or are spelt in imitation of French orthography; e.g. djebel, variant of jebel n., djerid, djereed, variants of jerid n., djin, variant of jinn n., djubbah, variant of jubbah n. So far as these come under the scope of this Dictionary, they will be found under J; for djowr ‘an infidel’ see giaour n.
