Collective nouns in Persian grammar, also known as “اسم جمع” (esm-e jam’), are the words used to describe a group or collection of similar items or people as a single entity. They play a pivotal role in the Persian language, just as in many other languages, helping to make your speech and writing clearer and more interesting. Unlike English, Persian uses different forms of collective nouns to differentiate between a small set, a limited set, and an unlimited set. They are usually straightforward to use and are an integral part of an advanced learning journey for Persian learners.
