Learn Farsi: کابل باید به پریز وصل شود. - The cable must connect to the socket.

You can simply add mâgar na? or in-tor nist? to the very end of the sentence. For example: Kâbl bâyad be pariz vasl shavad, mâgar na? Both phrases act like saying 'is it not so?' in English.

Why is the verb at the end shavad instead of mishavad?

This happens because of the word bâyad (must). In Farsi, when a verb follows bâyad, it changes to the subjunctive form. For the helper verb shodan (to become), the present subjunctive drops the mi- prefix and becomes shavad.

Why does the verb use shavad (to become) for 'connect'?

In Farsi, 'to connect' is a compound verb. Because the cable is receiving the action or getting connected, Farsi uses vasl (connection) plus shodan (to become). If a person were actively doing the connecting, you would use kardan (to do) instead, making it vasl kardan.

The word pariz (socket) sounds a bit unusual. Where does it come from?

Pariz is a loanword from the French word 'prise' (plug or socket). Farsi borrowed many modern technological and household words from French. Similarly, kâbl is also a loanword!
