Learn Farsi: میری فرودگاه؟ باهاش برو. - Are you going to the airport? Go with him.

In spoken Farsi, the preposition به (to) is frequently dropped before destinations when using verbs of motion like رفتن (to go). Saying میری فرودگاه is perfectly natural and much more common in casual conversation than the formal به فرودگاه می‌روی.

Where does the word باهاش (with him) come from?

باهاش (bahash) is the standard spoken contraction for با او (with him/her) or با آن (with it). It combines با (with) and the pronoun suffix ـش (him/her/it), using ها as a bridge. You will hear this constantly in everyday speech instead of the written forms.

The translation asks about a future plan, but isn't میری just the present tense?

Yes, میری is the present continuous tense (you are going). Just like in English, Farsi commonly uses the present tense to ask about immediate or planned future actions. Using the actual future tense here would sound far too formal for a casual conversation.

Why does the command form برو (go) start with an "o" sound (bo-) instead of the usual "be-" prefix?

To make a command (imperative) in Farsi, you usually add the prefix بـ (be-) to the present stem. The present stem of رفتن (to go) is رو (ro). Because the stem itself has an "o" sound, the prefix naturally changes its pronunciation from "be-" to "bo-" to match, resulting in برو (boro).
