The spelling of the word "Carualho" can be explained using International Phonetic Alphabet (IPA) transcription. The first sound is "k" and the second sound is "a," pronounced as "uh." The third sound is "ɾ," which is similar to the English "r" but is tapped instead of being pronounced with the tongue curled back. The fourth sound is "w," followed by "ɐ," pronounced as "ah." The final sound is "ʎ," which is similar to the English "ll" in the word "mill." Therefore, the correct spelling of this word would be "Carualho."
