A preverb is a morpheme, which is applied together with the participles modifying their meaning and the meaning of their derivates. Some Persian preverbs, referred to as "pīš fi'l" or "pīšvand e fi'l", are: • bar (meaning up, upon, from
Middle Persian abar) • bar (meaning fruit, from
Middle Persian bar) • bar (bar meaning chest, side, direction, from
Middle Persian war) and var (alternative form of bar) • bāz • far and fara • farāz • foru and forud • ham and an • ni • go (e.g godāxtan, gozāštan, gorīxtan, etc...) • negah and negāh • pas • piš • ru • sar • vā • andar and dar • pay • ā • tar and tara • par and para Pre-verbs can modify the procedure attribute of the verbs and the infinitives, but they do not change their objective attribute: {{fs interlinear|indent=2 {{fs interlinear|indent=2 The Pre-verb is normally positioned ahead of the verb. If the verb is composed of two separable components, the pre-verb is positioned ahead of the second component. The Pre-verb can be positioned at the end of the sentence, owing to versification requirements: از کارِ خير عزمِ تو هرگز نگشت باز هرگز زِ راه بازنگشتهست هيچ تير Manuchehri (11th - 12th Century AD) == Pingelapese ==
