The word "more sustentative" is spelled as /mɔːr səsˈtɛntətɪv/. The first sound is the long "o" as in "more," followed by "s" sound, and "uh" sound as in "the" and "uh-oh." The next part "sustentative" starts with "s" again, then "uh" as in "the," followed by "stent" sound, and "uh-tiv" at the end. This word means "more sustaining or nourishing," and is often used in the context of food or nutrition.
