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.
