Alphabet

Wenedyk uses the Polish alphabet, which consists of the following 32 letters:

A Ą B C Ć D E Ę F G H I J K L Ł M N Ń O Ó P R S Ś T U W Y Z Ź Ż

Besides, there are six "fixed" consonant clusters:

Ch Cz Dz Dź Rz Sz

I will not elaborate here about the interference between the different sounds. More about the phonological development of Wenedyk from Vulgar Latin can be found in my Grand Master Plan (a term borrowed from other conlangers who created Romance languages based on regular sound changes from Latin).

Stress

Stress is almost always placed on the penultimate syllable of a word. The combination of a preposition with a pronoun is treated as one entity: when the latter consists of only one syllable, the preposition is stressed, otherwise it remains unstressed.


Notes

(1) Ą and ę are rarely pronounced as real nasal vowels. Normally, they assimilate with the following consonant: kątar is pronounced as ['kOntar], lęgwa as ['lENgwa], kąp as [kOmp], przędzier as ['pSEJd_z\er], etc. At the end of a word ą is usually pronounced [O], followed by a very short and slightly nasalised [U] [OU(~)], while ę normally sounds like [E].

(2) It depends on the speaker, but in general s, z, c, and dz, are pronounced like dental spirants. An alveolar pronunciation would not be incorrect, though.

(3) There is no difference in pronunciation between ch and h. The pronunciation [x] is not entirely adequate, because there is less friction involved than in a real fricative.

(4) Some people call them retroflexes, others call them postalveolars or alveolars; for the sake of convenience I call them postalveolars.
