Aglossostoma is a rarely used medical term that refers to a condition where an individual is born without a tongue. The word follows the phonetic transcription [æ.ɡlɒs.ə.stəʊ.mə], wherein 'agloss-' denotes the lack of a tongue, and '-stoma' refers to the mouth or oral cavity. The word may seem complex, but it can be broken down into its constituent parts to help with understanding. Even though this may not be a commonly used term, accessing and understanding obscure medical language is important for healthcare professionals in different fields.
