Spoken Persian: plural you and definite nouns (میرین, پسره)

Your spoken verb endings so far cover he, she and they: میره، میرن. Two final pieces complete the conversational toolkit: talking to a group — and pointing at "that guy".

You All: ـید Becomes ـین

In spoken Persian the 2nd-person plural ending ـید relaxes to ـین:

WrittenSpoken
می‌رویدمیرین
می‌خواهیدمی‌خواین
می‌کنیدمی‌کنین
Are you all going to the market tomorrow?
فردا میرین بازار؟fardâ mirin bâzâr?

Remember that شما is also the polite way to address one person — so you will hear میرین said, politely, to a single stranger:

That Guy: the Suffix ـه

Spoken Persian marks a noun as "the one we both know" with the suffix ـه: پسر (a boy) → پسره (the boy, that guy):

SpokenEnglish
پسرهthe boy, that guy
دخترهthe girl

Before the copula, the suffix joins the ـست form you know from vowel-final words: پسره‌ست.
