A preposition meaning the definite article "the", or the relative pronouns "that", or "who" (as in "a boy who reads"). For example, yeled, a boy; hayeled, the boy.
A prefix indicating that the sentence is a question. (For example, Yadata, You knew; Hayadata?, Did you know?)
A suffix after place names indicating movement towards the given noun. (For example, Yerushalayim, Jerusalem; Yerushalaymah, towards Jerusalem.)
The hāʾ suffix appended to a verb represents a masculine object (e.g. يَقْرَأُهُ, yaqraʾuhu, "he reads it").
He, representing five in gematria, is often found on amulets, symbolizing the five fingers of a hand.
He is often used to represent the name of God, as He stands for Hashem, which means The Name and is a way of saying God without actually saying the name of God. In print, Hashem is usually written as He with a geresh: ה׳.
