Abstract

Brazilian Portuguese has a vowel harmony rule which consists of the optional raising of the pretonic e and o vowels to i and u, respectively, if there is a high vowel in the following syllable. This is an old rule, the origin of which can be traced back to the Latin of the 4th century a.d. Because the rule is subject to multiple conditioning by both linguistic and social factors, it can be treated as a variable rule.
