Modal Verbs in Persian language, also known as فعل حالت (Fe`l-e haalat), play a crucial role in forming phrases and sentences. These verbs express functions such as likelihood, ability, permission, or obligation, much like they do in other languages. The main modal verbs used in Persian include میتوان (can), باید (must), شاید (might), and قرار است (is supposed to). Understanding and learning to use these modal verbs correctly is essential for mastering Persian grammar.
