Achroglobin is a relatively uncommon word that is spelled using a combination of Greek and Latin roots. It refers to a protein found in the blood that is responsible for transporting oxygen. The phonetic transcription of the word is əˈkrəʊɡləʊbɪn, indicating that it is pronounced with a short schwa sound followed by the stressed syllable "krəʊ" (like "crow") and a short "o" sound in the second syllable. The final syllable "bin" is pronounced like "bin" or "been" depending on the accent.
