Usage
Polish
In the Polish language, ż is the final, 32nd letter of the alphabet. It typically represents the voiced retroflex fricative, somewhat similar to the pronunciation of in "mirae"; however, in a word-final position or when followed by a voiceless obstruent, it is devoiced to the voiceless retroflex fricative.Its pronunciation is the same as that of the digraph, except that also undergoes devoicing when preceded by a voiceless obstruent. The difference in spelling comes from their historical pronunciations: ż originates from a palatalized or, while evolved from a palatalized.
The letter was originally introduced in 1513 by Stanisław Zaborowski in his book Ortographia.
Occasionally, the letter Ƶ ƶ is used instead of Ż ż for aesthetic purposes, especially in all-caps text and handwriting.
