Некоторые особенности глагольной акцентуации в староштокавских памятниках XV в.
Previously it has been found that while the a.p.a in Serbian manuscriptsis is stable, reflection of the a.p.b shows diversity. It has been established in particular (Dybo 1983) that in Ev.-apr. and Sborn. the etymological root length is relevant for the accentuation in present forms of a.p.b j-praesentia: in 1SgPrae the long-root prefixed verbs demonstrate prefix-stress, the short-root demonstrate root-stress.
My general accentological investigation of old-Štokavian manuscripts (Apost., Ev.-apr., Sborn.) reveals the following facts:
The prefix-stress should be regarded as the basic variant for prefixed long-root a.p.b j-praesentia in 1SgPrae; root-stressed forms in Sbor. can be treated as secondary. Appropriate forms of short-root verbs have stable root-stress. In non-prefixal a.p.b j-praesentia, both with long and short roots, two variants of 1SgPrae compete, root-stressed and flexion-stressed. Therefore for non-prefixed verbs, the root length is irrelevant for accentuation.
The root length opposition also affects the accentual behavior of a.p.b nu-verbs. Here the form of 2-3SgAor without ‑nu‑suffix is significant. These forms from long-root prefixed verbs are prefix-stressed; in short-root verbs root-stressed and flexion-stressed variants coexist. So the prefixed nu‑verbs relate to the root-length opposition in aorist similarly as the j-praesentia in presence.
These features of verbal accentuation can be interpreted as coexistence of two accentuation strategies: "paradigmatic" and "categorial".
