The
phonological system of the Kashubian language is similar in many ways to those of other
Slavic languages. The
Kashubization of consonants a distinguishing feature of Pomeranian lects. Kashubian has a large
vowel inventory, with 9 oral vowels and 2 nasal vowels.
Vowel length Friedrich Lorentz argued that northern dialects had contrastive vowel length, but later studies showed that any phonemic length distinctions had disappeared by 1900. Any other vowel length is used for expressive purposes or is the result of syllable stress. All traces of vowel length can now be seen in vowel alterations.
Syllable stress Kashubian features free placement of
stress, and in some cases, mobile stress, and in northern dialects, unstressed syllables can result in
vowel reduction. An archaic word final stress is preserved in some two-syllable adjectives, adverbs, and regularly in the
comparative degree of adverbs, in some infinitives and present and past tense forms, some nouns ending in
-ô, in
diminutives. ending in
-ik/
-yk, nouns formed with
-c and
-k, and some prepositional phrases with pronouns. Stress mobility can be observed in nouns, where in the singular the stress is initial, but in the plural it's on the final syllable of the stem, i.e. but , and in some verb forms, i.e. vs . Some dialects have merged
ë with
e, making the distinction contrastive. Most of this mobility is limited to morphology and stress has largely stabilized in Kashubian. Northern and central dialects show a much more limited mobility, as northern dialects show stabilization on initial stress, and central shows constant distance between the stressed syllable and the initial syllable of the word.
Proclitics such as prepositions, pronouns, and grammatical particles such as may take initial stress. Eastern groups place accents on the penultimate syllable. The difference between southern and northern dialects dates as far back as the 14th–15th century and is the result of changes to the
Proto-Slavic vowel length system.

Consonants Kashubian has simple consonants with a secondary articulation along with complex ones with secondary articulation. • are
palato-alveolar. • are
alveolo-palatal; the last four appear only in some dialects. • The fricative trill is now used only by some northern and northeastern speakers; other speakers realize it as flat postalveolar . • The labialized velar central approximant is realized as a velarized denti-alveolar lateral approximant by older speakers of southeastern dialects.
Voicing and devoicing Kashubian features the same system of voicing assimilation as
standard Polish.
Vocabulary German has been the source for most loanwords in Kashubian, with an estimated 5% of the vocabulary, as opposed to 3% in Polish. Kashubian, like other Slavic languages, has a rich system of derivational morphology, with prefixes, suffixes, deverbals, compounds, among others. == Orthography ==
