Mucific is a rare word that refers to something that produces or promotes the production of mucus. Its pronunciation is [myu-sif-ik], with the stress on the second syllable. The "muc" syllable in the beginning is pronounced like "myu" in the IPA (International Phonetic Alphabet), followed by the short "sif" sound and the stressed "ik" at the end. The spelling of Mucific derives from the Latin root "mucosus", which means slimy or mucus-like, combined with "-fic", a suffix meaning to make, produce, or cause.
