• When attached to averbal root,prefixes often change the firstvowel (whether initial or preceded by a consonant/consonant cluster) of that verb. These phonological changes took place in Latin and usually do not apply to words created (as inNew Latin) from Latin components sinceLatin became a 'dead' language. Note: the combination of prefix and following vowel did not always yield the same change. Also, these changes in vowels are not necessarily particular to being prefixed with dis- (i.e. other prefixes sometimes cause the same vowel change- seecon-,ex-).

NOTE: Words using the prefixdis- do not necessarily use the prefixes given here when translated. See individual words for more accurate translations.
