القواعد

In Arabic, there are two types of noun and adjective plural forms: sound (regular) plurals, and broken (irregular) plurals. Masculine sound plural nouns end in ون and feminine sound plural nouns end in ات.

Usually feminine inanimate nouns that end in ta marbuta take the feminine sound plural.

There are some important exceptions to this rule though.

There are also some masculine nouns, usually borrowed words, that take the feminine sound plural.

The masculine sound plural is never used with inanimate nouns.
