The correct spelling of the phrase "more big name" is "more big-name." The hyphen is important because it clarifies that "big-name" is a compound adjective modifying the noun "more." In IPA phonetic transcription, the word is pronounced as /mɔːr bɪɡ neɪm/. This means that the first syllable is pronounced as "more" with a long vowel sound, followed by "big" with a short "i" sound, and "name" with a long "a" sound.
