The spelling of the name "Roddick" can be explained through its IPA phonetic transcription. The first syllable "rod" is represented by the phonemes /r/ and /ɒ/, which together create the sound of the letter "o" as in "hot". The second syllable, "dick", consists of the phonemes /d/ and /ɪ/, which create the sound of the letter "i" as in "sit". Therefore, "Roddick" is spelled with two "d"s and an "o" and "i" in its pronunciation.
