The spelling of "more fusing" can be quite confusing due to the presence of two silent letters. The correct pronunciation is /mɔːr fjuːzɪŋ/, with emphasis on the second syllable. Here, "more" is pronounced as "mawr" and "fusing" as "fyoozing". The silent "e" at the end of "more" indicates that the preceding vowel is a long "o" sound, while the silent "u" in "fusing" indicates a long "u" sound in the first syllable. Despite its tricky spelling, "more fusing" can be a useful phrase to describe the process of combining or blending materials.
