The spelling of the word "more precedently" can be a bit tricky due to the use of the suffix "-ly" with the word "precedent" to indicate manner. The correct pronunciation of this term is /mɔːr prɪˈsiːdəntli/. The stress falls on the third syllable and the final "-t" sound in "precedent" is not pronounced. The word means "in a more preceding or prior manner." It is important to pay close attention to spelling and pronunciation when using complex words like this one.
