The spelling of the word "mattila" can be tricky because of the double letter "t" and the double vowel "i." The IPA phonetic transcription helps to clarify the pronunciation: /ˈmætɪlə/. The first syllable is pronounced with a short "a" sound (like in "cat"), followed by a double "t" sound. The second syllable has a short "i" sound (like in "sit"), followed by a double "l" sound. The final syllable has a schwa sound (like in "about").
