The glottis is a part of your throat near your vocal cords that controls airflow and helps produce sound when you speak, sing or make other vocal sounds. It's important for speaking and swallowing. If you're learning English, you might hear the term "glottis" used in a medical or scientific context, or in discussions of voice and speech. It's not a word you'll use in everyday conversation unless you work in a field related to language or voice production.
