Rhodeia is a word that is spelled with an "e" between "Rhod" and "ia." This is because the word comes from the name of the Greek island of Rhodes, which is pronounced with a long "o" sound (IPA: roʊdz). The "e" is added to keep the same sound in the spelling of the word. The IPA transcription for Rhodeia would be "roʊ-di-ə," with the "e" representing the schwa sound that occurs between the "d" and "i" sounds.
