Persian is the most widely spoken member of the Iranian branch of the Indo-Iranian languages. It is the official language of Iran and is also widely spoken in Afghanistan and, in an archaic form, in Tadjikistan and the Pamir mountain region.
Persian verbs are very regular compared with those of most European languages. From the two stems given in dictionaries (e.g. gir, gereft 'take, took', nevis, nevešt 'write, wrote', deh, dād 'give, gave' etc.) it is possible to derive all the other forms of almost any verb. The main irregularity is that given one stem it is not usually possible to predict the other.
Persian verbs are inflected for three singular and three plural persons. The 2nd and 3rd person plural are often used when referring to singular persons for politeness.
