تو

تو (to) is the intimate Persian “you”. Use it wrong and you sound like you’re either confessing love or starting a fight.

What it actually means

تو is the second-person singular pronoun in its intimate form. Persian splits the English “you” into two pronouns: تو for close, equal, or downward relationships (lovers, siblings, close friends, children, pets, God in prayer), and شما (shomâ) for formal, older, or unfamiliar listeners. This is the classic T-V distinction, the same split French has between tu and vous. Picking the right one is the single most consequential register choice in Persian. Use تو with the wrong person and you’ve insulted them; use شما with someone who expects تو and you’ve put a wall between you. Iranians read this choice instantly and form opinions from it. تو also gets used downward in anger (“تو خفه شو!” = “you shut up!”), in poetry addressed to the divine beloved, and in any context where intimacy or hierarchy collapses formality.

How to say it

How to use it

• تو کجایی؟ · to kojâ-yi? · Where are you? (close friend)
• دوستت دارم. · dustet dâram. · I love you (verb ending matches تو).
• تو بهتر می‌دونی. · to behtar miduni. · You know better.

Cultural note

Switching from شما to تو with someone is a small ceremony. Iranians sometimes ask permission for it: “می‌تونیم تو باشیم؟” (can we be on “to” terms?). It marks the moment a relationship moves from polite distance to closeness. Lovers always use تو once they’re together, even if they were شما while dating. Parents say تو to children; children traditionally say شما back to parents, though urban modern families often go تو in both directions. In Persian poetry, especially Sufi verse, the divine beloved is addressed as تو, which carries enormous tenderness: Hafez and Rumi talk to God the way you’d talk to your closest friend.
