The word "sarcogenic" is spelled with a "c" rather than a "k" sound. This is because it is derived from the Greek word "sarkos," meaning flesh, which is spelled "σάρκα" in Greek. The "c" sound in "sarcogenic" corresponds to the Greek letter "gamma" (γ) which represents the "g" sound before the vowels "a," "o," and "u," and the soft "ng" sound before the vowels "e" and "i." The IPA phonetic transcription for "sarcogenic" is /sɑrkəˈdʒɛnɪk/.
