The word "anamnionic" is not commonly used in everyday language but can be found in medical or scientific contexts. Its spelling is based on the Greek word "anamnesis," meaning recollection or reminiscence. In IPA phonetic transcription, it is pronounced /ˌænəmniˈɑnɪk/, where each symbol represents a specific sound. The "a" and "o" sounds are pronounced like the "a" in "cat" and "o" in "pot," respectively. The double "n" represents a nasal sound, and the stress is on the third syllable.
Without an amnion, anamniotic.
