There are several suffixes in Hebrew which are appended to regular words to introduce a new meaning. Suffixes are used in the Hebrew language to form plurals of nouns and adjectives, in verb conjugation of grammatical tense, and to indicate possession and direct objects. They are also used for the construct noun form. The letters which form these suffixes (excluding plurals) are called "formative letters" (Hebrew: אוֹתִיּוֹת הַשִּׁמּוּשׁ, Otiyot HaShimush).
