The spelling of the word "rodda" is unique and may seem puzzling. However, it can be explained using the International Phonetic Alphabet (IPA). The word is pronounced as /ˈrɒdə/ with the stress on the first syllable. The double "d" in the spelling indicates that the preceding vowel sound is short, which is common in English. Additionally, the use of the letter "a" in the final syllable indicates the vowel sound as the "schwa" or a neutral vowel. Therefore, the spelling of "rodda" accurately represents its phonetic pronunciation.
