The spelling of the word "Lukacz" is rather unique in that it contains two consonants not frequently found together in English words. The 'cz' combination is actually a digraph in Polish, representing the voiceless alveolo-palatal affricate consonant /tʂ/. When pronounced, the word "Lukacz" would be said as /luːkɑːtʂ/, with the stress on the first syllable. This word can pose a challenge for those who are not familiar with Polish pronunciation or its particular alphabet.
