The spelling of the word "Marrlin" is actually incorrect. The correct spelling is "Marlin." The word is pronounced /ˈmɑrlɪn/ in IPA phonetic transcription. The "a" and "i" combination creates the "ai" diphthong sound, which is pronounced like the "igh" in "sigh." The single "r" is pronounced with a slightly rolled tongue, and the final "n" is pronounced with a nasal sound. It's important to use correct spelling and pronunciation to effectively communicate ideas and avoid confusion.
