In Hebrew, the potential imperfect is a verb form used to express possibility or potentiality. It is formed by adding the prefix יִ (yi-) to the verb root, followed by the appropriate conjugation suffix. For example, the potential imperfect of the verb לִרְאוֹת (to see) would be יִרְאֶה (yireh), meaning "he might see" or "he could see."
