When a Hebrew demonstrative is functioning as a pronoun, it will typically replace the noun it refers to and agree in both gender and number. This means that the demonstrative pronoun will match the gender (masculine or feminine) and number (singular or plural) of the noun it is replacing. This agreement helps to clarify which specific noun is being referred to in the context. For example, "zeh" (זֶה) is a masculine singular demonstrative pronoun, while "zot" (זֹאת) is a feminine singular demonstrative pronoun in Hebrew.
