Over the centuries, Old Polish pronunciation underwent several
changes.
Consonants The early Old Polish consonantal system consisted of the following
phonemes. Since the precise realization of these sounds is unknown, the transcriptions used here are meant to be approximations. The sound [d͡ʒ] only occurred in the cluster [ʒd͡ʒ], therefore its phonemic status is doubtful. The most important consonantal changes concerned the realization of the
soft coronal consonants. Of these, /tʲ/, /dʲ/, /sʲ/ and /zʲ/ strengthened their palatalization and became
alveolo-palatal, and the former two were
affricated. The resultant sounds were similar to their
modern Polish counterparts: /t͡ɕ/, /d͡ʑ/, /ɕ/ and /ʑ/. This change happened very early, starting already in the 13th century as evidenced by spelling. Somewhere around the 13th to 14th century, the phoneme /rʲ/ came to be pronounced with considerable friction, probably resulting in a sound similar to Czech /r̝/ (but by then probably still palatalized: /r̝ʲ/). The
Proto-Slavic language did not have a /f/ phoneme. In the 12th and 13th century in the dialects of
Lesser Poland and
Masovia the initial
clusters /xv/ and /xvʲ/ were simplified to /f/ and /fʲ/ (e.g. > , > , > ). This enlarged their consonantal inventory by two. This change did not make it to the
literary language, and was ultimately reversed also in those dialects. But before that, in the 14th and 15th century these two sounds became firmly established in
borrowings (in earlier loanwords foreign [f] was replaced by either /b/ or /p/). Perhaps one of the oldest loanwords which keeps /f, fʲ/ unchanged is the word ("victim; offering"), loaned from Czech , since the pre-writing era change
ě>
a before a hard consonant () seemed to have operated in it. /f/ also appeared later from the reduction of the cluster /pv/ (chiefly in the word > and
derivatives). The very end of the Old Polish period (15th–16th century, so during the transition to
Middle Polish) saw the palatalization of the velar plosives /k/ and /ɡ/ before front oral vowels to [kʲ] and [ɡʲ], named the so-called "fourth Slavic palatalization". This distinction was later phonemicized with the introduction of borrowings which had hard velars before front vowels, as well as the denasalization of word final /ɛ̃/. Note that this change did not affect the velar fricative /x/ or velars before the front nasal vowel /æ̃~ɛ̃/. Not all regional varieties handled this change in the way here described, most notably in
Masovia. After these alternations, the late Old Polish consonant system presented itself thus:
Vowels The early Old Polish vocalic system consisted of the following
phonemes. As mentioned, the sound qualities are approximations. [ɨ] and [ɨː] were in
complementary distribution with [i] and [iː] respectively – the former occurred after hard consonants, the latter in all other positions. The pairs can therefore be regarded as
allophones. All vowel phonemes occurred in pairs, one short and one long. Long vowels emerged in Old Polish from four sources: •
compensatory lengthening of vowels in penultimate syllables followed by a
voiced consonant and a word-final
yer, which was deleted (see
Havlík's law) • examples: PS
*rogъ > OP
rōg, PS
*gněvъ > OP
gniēw, PS
*stalъ > OP
stāł • from the
contraction of various sequences of two vowels separated by /j/ • examples: PS
*sějati > OP
siāć, PS
*dobrajego > OP
dobrēgo, PS
*rybojǫ > OP
rybǭ • inherited from
Proto-Slavic neoacute accent • examples: PS
*pъtákъ > OP
ptāk, PS
*sǫ̃dъ > OP
sø̄d, PS
grě̃xъ > OP
grzēch • inherited from
Proto-Slavic pretonic long vowels in two-syllable words (so long vowels in the first syllable if the second syllable was final and stressed) • examples: PS
*mǭkà > OP
mø̄ka, PS
*dě̄žà > OP
dziēża, PS
*dōltò > OP
dłōto Due to the lengthening described in 1. short vowels could not occur in word-final syllables before a voiced consonant. The only exceptions was short /ɛ/ from an older strong yer.
Prostheses Similarly to some other
Slavic languages and
dialects, there existed a tendency to constrain the occurrence of vowels in word onset. A
prosthetic [j], [w] or [h] was often introduced to words beginning with a vowel: • Earlier
*e,
*ě received a prosthetic [j] already in Late Common Slavic: PS
*edinъ > OP
jeden, PS
*ěsti > OP
jeść. An exception was the dialectal
conjunction eż,
eże. • Earlier
*ę,
*ǫ were also preceded by a prosthesis since the oldest records, [j] and [v] respectively: PS
*ęzykъ > OP
język, PS
*ędro > OP
jꟁdro, PS
*ǫtroba > OP
wꟁtroba, PS
*ǫgľь > OP
węgiel. To this day nasal vowels cannot begin a word in Polish. • Earlier
*a received a prosthetic [j] similarly to front vowels: PS
*agoda > OP
jagoda. Once again, an exception to this was a conjunction –
a, very common to this day, as well as its
derivatives:
ale,
aż,
ani etc. • Old Polish rounded vowels /ɔ, ɔː/ probably had a labial prosthesis [w], as is universal in dialects (e.g. [wɔkɔ] – /ɔkɔ/ – "oko"), but it was seldom marked in writing. Sometimes the spelling points to a prosthetic [h] instead, for both /ɔ, ɔː/ as well as /u, uː/ (
a hon – "a on";
hupana Jana – "u pana Jana"). • Old Polish /i, iː/ seemed to have had a rather strong prosthetic [j], often made evident in spelling (np.
gymyenyu [jimʲɛɲu] – "imieniu"). More rarely also [h] occurred. • Loanwords were also affected, e.g.
Jadam instead of "Adam",
Jewa instead of "Ewa",
Helska as a shortened form of "Elżbieta" ("Elizabeth").
Loss of vowel length During the Old Polish period,
vowel length ceased to be a feature distinguishing phonemes. The long high vowels /iː/, [ɨː] and /uː/ merged with their short counterparts, with no change in
quality. The fate of the remaining long oral vowels was different; they also lost their length, but their articulation became more
closed and so they remained distinct from their old short counterparts. Thus, /ɛː/ changed to /e/ and /ɔː/ changed to /o/. The earlier long /aː/ also gained
roundedness and became /ɒ/. This process was long and only complete by the late 15th century. The higher vowels are traditionally called ("skewed") in Polish. The
nasal vowels developed differently. Old Polish continued to have four nasal vowels until the 14th century, when they merged in respect to quality, but retained the length distinction. Therefore, the new system had only two nasal vowels: short /ã/ (from earlier /æ̃/ and /ɑ̃/) and long /ãː/ (from earlier /æ̃ː/ and /ɑ̃ː/). In the 15th century when vowel length was disappearing the two nasals retained the old length distinction through changes in quality, like the other non-high vowels. The short nasal was fronted to /æ̃~ɛ̃/ and the long backed to /ɒ̃~ɔ̃/ and lost its length (both with differing dialectal realizations). The described changes led to the creation of the late Old Polish vocalic system:
Accent Although
stress was never marked in writing, its development in Old Polish can be partially inferred from certain other phonetic changes. In older works, the
verbal
suffix -i/
-y of the 2nd & 3rd ps. sg. imp. is dropped in some verbs, but retained in others. A comparison with
East Slavic languages shows that the suffix remained when it was stressed in Proto-Slavic. Examples: •
Bogurodzica – • Bogurodzica – • Bogurodzica – •
Sankt Florian Psalter – Because of this and other evidence, it is thought that early Old Polish had free, lexical stress inherited from Proto-Slavic. Occasional
ellipsis of the second vowel in commonly used trisyllabic words and phrases in the 14th and 15th century ( > , > , > , > ) point to the conclusion that by that time fixed initial stress had developed. The initial stress in the peripheral
Podhale and southern
Kashubian dialects (now considered a separate language but still part of the
Lechitic dialect continuum) are taken to be remnants of earlier widespread initial stress. In the case of Podhale,
Slovak influence is usually ruled out, because Slovak dialects bordering Podhale have penultimate rather than initial stress. == Morphology ==
