A Nazm is a type of poem with a common theme, often about the human existence and written in the Urdu language, which sees much use in not just Pakistan but also Northern India.
Each Nazm has a central theme that runs throughout the entire poem, meaning that its individual lines and couplets cannot be interpreted on their own. This is in contrast to another popular type of Urdu poetry called the ghazal, which can have independent verses with independent meanings of their own. Besides this restriction, the Nazm tends to be much less constrained than its counterpart in the ghazal. For example, the Nazm can cover a wide range of topics, whereas the ghazal has a strong focus on the love of various sorts. Likewise, the Nazm can see enormous variation in its length, with some examples being either much shorter or much longer than others. Finally, there are the no rules on either the length of the lines or whether specific syllables have to rhyme with one another because the writer of the Nazm is the one who decides how they want to write it.
