The spelling of the word "gerena" can be a bit tricky to decipher phonetically. In IPA transcription, it is written as /d͡ʒəˈɹiːnə/. The first sound is a voiced palato-alveolar affricate, similar to the "j" in "jungle." The next sound is a schwa, which is a short "uh" sound. The "r" is pronounced with a retroflex tongue position, and the next sound is a long "e." The last sound is pronounced with a short "uh" sound, similar to the second sound.
