Two of the listed templates feature an added yāʾ: فَيْعَلَة and فَعْيَلَة. The yāʾ appears in a different position in each pattern, changing the full template.
حَيْعَلَة — in this source list, wearing a sleeveless garment.
شَرْيَفَة — cutting overgrown crop leaves.
The two forms cannot be treated as interchangeable. The location of yāʾ within the verbal-noun pattern is a grammatical distinction, not merely a spelling detail.
