The word "Marined" is spelled with the letter "d" at the end, despite being pronounced with a final "-t" sound. This is because it is a regular verb in English and follows the rule that verb forms in the past tense are formed by adding "-ed" to the base form. In IPA phonetic transcription, the pronunciation of "Marined" would be /məˈriːnd/, with the emphasis on the second syllable and the final sound represented as a "d" even though it sounds like a "t".
