perienth

Spelled perianth. an unstressed vowel

The seam in perianth falls between the i and the a.

Peri plus anth. Perienth puts an e where the a of anthos has to be.

Two vowels meet at that join and neither one is stressed, so they blur into each other and arrive as a single indistinct sound. Splitting the word at the seam is the reliable way back: peri, around, and anth, flower.
