The correct spelling of "more split second" is /mɔː/ /splɪt/ /ˈsɛkənd/. This term refers to an even shorter amount of time than a split second, and is commonly used in sports and other fast-paced activities. The pronunciation of each individual syllable is important to ensure the word is correctly understood by others. The use of IPA phonetic transcription helps to clarify the sounds that make up the word and allows for consistent pronunciation among speakers.
