The development of suprasegmental features in Proto-Slavic is treated in 3.2.4.
All three features have been eliminated, at some time, by at least one of the Slavic
languages. In the modern languages, furthermore, we find important interrela-
tions between the three features. Stress and pitch are directly related in Slovenian
and B/C/S, and the two always occur on the same vowel. In languages with
phonemic stress, stressed vowels are generally longer than the unstressed ones,
as in English. Pitch and length can function separately, as in B/C/S, where post-
tonic vowels may be long or short. They can be partially interdependent, as in
Slovenian, where only long vowels may carry a tonal opposition. B/C/S quantity
is therefore freer (¼ less conditioned) than that of Slovenian. Similarly, the
existence of the Slovak Rhythmic Law (3.5.2) means that quantity in Slovak is
less free than in C zech.
By combining these factors, we arrive at the following classification of the modern
Slavic languages according to their suprasegmental features (see also 3.2.4):
No distinctive suprasegmental features: Polish, Sorbian, Macedonian
Stress only: East Slavic, Bulgarian
Quantity only: Czech (free), Slovak (limited)
Stress and (limited) quantity: Slovenian (non-tonal variant)
Stress, tone and quantity: B/C/S, Slovenian (limited quantity and pitch)
Sentence intonation is also a prosodic feature of Slavic. But there are few com-
parative studies of Slavic intonation (Nikolaeva 1977; Bahmut, 1977 for East
Slavic), and no generally agreed framework for analysis or description. We conse-
quently omit intonation from our discussion of phonology, though some aspects
will be noted in chapter 7.
3.5.1 Stress
While early Proto-Slavic probably developed fixed penultimate or final stress, later
stress was determined by the location of pitch while this could still appear on any
syllable. Eventually it became associated with particular morphemes and inflex-
ional patterns, and became free, at which point pitch became limited to the stressed
syllable, and so was secondary. The pitch accent has given way to stress in nine of
the eleven languages, and five of them now have fixed stress.
The accent pattern of the modern Slavic languages can be classified as follows.
Stress (free and mobile):
1. Intensity: East Slavic, Bulgarian, Slovenian non-tonal
2. Pitch: B/C/S, Slovenian tonal
