From a synchronic point of view, the accentuation of Late Polabian has been clarified by Trubetzkoy (1929) and Olesch (1973, 1974). The stress fell on the last full vowel of a word form, which was found either in the final or in the penulti-mate syllable. In the latter instance, the final syllable contained a reduced vowel. This rule was challenged by Kurylowicz (1955), who maintained that the stress was fixed on the initial syllable of the word. The latter theory has the advantage of accounting for the absence of reduced vowels in initial syllables.
