disen-, disem-Verbs in dis- are sometimes in sense negative or privative of those in em-, en-: e.g.en-franchise, dis-franchise; generally, however, verbs in em- or en- have dis- prefixed, as in dis-embarrass, dis-engage, dis-entwine. In not a few cases, both forms occur; e.g.disbowel=disembowel, disfranchise=disenfranchise. Forms in disem- and disen- are found even where no verbs in em- or en- appear, as in disemburden, disenhallow, disenravel.
