 The early development of the Glagolitic minuscule script alongside the increasingly square majuscule is poorly documented, but before the advent of printing, a mutual relationship evolved between the two varieties; the majuscule being used primarily for inscriptions and higher liturgical uses, and the minuscule being applied to both religious and secular documents.Ignoring the problematic early Slavonian inscriptions, the use of the Glagolitic script at its peak before the Croatian-Ottoman wars corresponded roughly to the area that spoke the Chakavian dialect at the time, in addition to, to varying extents, the adjacent Kajkavian regions within the Zagreb bishopric.As a result, vernacular impact on the liturgical language and script largely stems from Chakavian sub-dialects.
