The spelling of the word "MCP" is straightforward when using the International Phonetic Alphabet (IPA). Each letter corresponds to a specific phonetic sound, with "M" representing the bilabial nasal sound /m/, "C" representing the voiceless palatal fricative sound /ç/, and "P" representing the voiceless bilabial plosive sound /p/. When pronounced correctly, the word will sound like "em-see-pee." This spelling is commonly used in medical terminology to refer to the metacarpophalangeal joint, which connects the hand bones to the finger bones.
