A prefix of Latin origin (in other forms di-, dif-), in force— separative or disjunctive, ‘apart,’ ‘asunder,’ ‘in different directions,’ etc., as in distend, dispart, dissident, etc., this force being often only indistinctly felt in the English word, as in dispose, dissent, distract, etc., and passing even in Latin into a merely intensive use, not felt at all in English, as in dispute; privative or negative, like the English un-, reversing or negativing the primitive, as in dissimilar, etc., having come, in this use, from its frequency in Middle Latin and Old French, to be recognized as a regular English prefix, and as such usable with almost any verb and adjective, as in disable, disesteem, disfavor, disoblige, disfellowship, etc., and in colloquial or dialectal use in such forms as disremember, disrecollect, etc. In some words the prefix dis- was early reduced by apheresis to s-, a form common in Italian, and seen in English in spend, splay, sport, etc., as compared with dispend, display, disport, etc.
