di 音标拼音: [d'i] [d'ɑɪ] n. (音乐) duo与 re中间的音 (音乐) duo与 re中间的音 Di- \ Di-\ [ Gr. di` s- twice; akin to ? two, L. bis twice. See { Two}, and cf. { Bi-}, { Dia-}. The L. pref. dis- sometimes assumes the form di-. See { Dis-}.] A prefix, signifying twofold, double, twice; ( Chem.) denoting two atoms, radicals, groups, or equivalents, as the case may be. See { Bi-}, 2. Dia
Dia- \ Di" a-\, Di- \ Di-\ . [ Gr. dia` through; orig., dividing into two parts; akin to ? two. See { Two}, and cf. 1st { Di-}.] A prefix denoting through; also, between, apart, asunder, across. Before a vowel dia- becomes { di-}; as, diactinic; dielectric, etc. [ 1913 Webster]
Deuto- \ Deu" to-\ or Deut- \ Deut-\ ( d[= u] t-)[ Contr. from Gr. dey` teros second.] ( Chem.) A prefix which formerly properly indicated the second in a regular series of compound in the series, and not to its composition, but which is now generally employed in the same sense as { bi-} or { di-}, although little used. [ 1913 Webster]
dis- \ dis-\ (?; 258) 1. A prefix from the Latin, whence F. d[' e] s, or sometimes d[' e]-, dis-. The Latin dis- appears as { di-} before b, d, g, l, m, n, r, v, becomes dif- before f, and either dis- or di- before j. It is from the same root as bis twice, and duo, E. two. See { Two}, and cf. { Bi-}, { Di-}, { Dia-}. Dis- denotes separation, a parting from, as in distribute, disconnect; hence it often has the force of a privative and negative, as in disarm, disoblige, disagree. Also intensive, as in dissever. [ 1913 Webster] Note: Walker' s rule of pronouncing this prefix is, that the s ought always to be pronounced like z, when the next syllable is accented and begins with " a flat mute [ b, d, v, g, z], a liquid [ l, m, n, r], or a vowel; as, disable, disease, disorder, disuse, disband, disdain, disgrace, disvalue, disjoin, dislike, dislodge, dismay, dismember, dismiss, dismount, disnatured, disrank, disrelish, disrobe." Dr. Webster' s example in disapproving of Walker' s rule and pronouncing dis- as diz in only one ( disease) of the above words, is followed by recent ortho[" e] pists. See { Disable}, { Disgrace}, and the other words, beginning with dis-, in this Dictionary. [ 1913 Webster] 2. A prefix from Gr. di` s- twice. See { Di-}. [ 1913 Webster]
Disserve \ Dis* serve"\, v. t. [ imp. & p. p. { Di?????}; p. pr. & vb. n. { Disserving}.] [ Pref. dis- serve: cf. F. desservir.] To fail to serve; to do injury or mischief to; to damage; to hurt; to harm. [ 1913 Webster] Have neither served nor disserved the interests of any party. -- Jer. Taylor. [ 1913 Webster]
