Madescent is a rarely used word, meaning "becoming or appearing less than before." The spelling of this word can be explained using IPA phonetic transcription as /meɪˈdɛsənt/. The first syllable is pronounced as "may" while the second syllable sounds like "dess" as in "dessert." The stress falls on the second syllable. The "-esc" ending is a rare variation of the more common "-escent" suffix denoting the process of emerging or becoming. Spelling and pronouncing rare words like "madescent" can add flavor and depth to our vocabulary.
