How many versions of the letter 'Z' does the Polish alphabet have?

There are 32 letters in the Polish alphabet: 9 vowels and 23 consonants.

The Polish alphabet is the script of the Polish language, the basis for the Polish system of orthography. It is based on the Latin alphabet but includes certain letters with diacritics: the kreska or acute accent (ć, ń, ó, ś, ź); the overdot or kropka (ż); the tailor ogonek (ą, ę); and the stroke (ł). The letters q, v and x, which are used only in foreign words, are frequently not considered part of the Polish alphabet. However, prior to the standardization of the Polish language, the letter "x" was sometimes used in place of "ks".

The letter Ż may be called żet (or zet) zet z kropką ("Z with a dot") to distinguish it from RZ (er zet). There are three versions of the letter Z that are used in the Polish alphabet:

Z z zet /z̪/ zoo (s̪) when devoiced.

Ź ź ziet /ʑ/ vision (alveolo-palatal) (ɕ) when devoiced.

Ż ż żet or zet z kropką /ʐ/ vision (ʂ) when devoiced.
