The spelling of the word "Aphistesis" can be a bit confusing since it is not a common word. It is pronounced /æfɪsˈtiːsɪs/, with the stress on the third syllable. The first two syllables are pronounced with the short 'a' sound, just like in the word "apple". The 'ph' in the third syllable is pronounced like an 'f', and the final 'esis' is pronounced with a long 'e' sound and a soft 's' sound. Despite its tricky spelling, this word actually has a simple meaning - it refers to the process of surgical stitching.
