The word "agomphious" is a rare adjective that means "not equipped with or without teeth." Its spelling may seem challenging, but it can be broken down phonetically as /əˈɡɒmfɪəs/. This indicates that the stress is on the second syllable, and the first syllable is pronounced with a schwa sound. The "g" is pronounced like a soft "j," and the "ph" is pronounced like an "f." Once the pronunciation is mastered, using this unique word can strike a distinguished tone in communication.
Without teeth, toothless.
