The word "haemoid" is a medical term that refers to something resembling blood or blood vessels. Its spelling is a result of using English spelling conventions to represent the Greek word "haima," meaning "blood." The "ae" spelling is a combination of the two vowel sounds in the Greek word, which are represented in IPA phonetic transcription as /hɛmoʊ/. The "-oid" suffix indicates something resembling the root word. Therefore, "haemoid" is pronounced as /ˈhiːmɔɪd/.
