The correct spelling of the phrase "study at predominant" involves several tricky elements. Firstly, the "o" in "predominant" is pronounced as a short "uh" sound, represented in IPA as /ə/. Additionally, the stressed syllable in "predominant" is the second syllable, represented as "dom" in IPA as /dɑm/. When combined, the correct spelling and pronunciation of the phrase is "STUD-ee at pree-DAH-mə-nuhnt." Remembering these elements can be challenging, but practicing with IPA can help improve one's spelling abilities.
