Questions & Answers about Ukoliko PIN ne radi, pozovite banku.

What does ukoliko mean here, and is it the same as ako?

Ukoliko means if in this sentence. Yes, it is very close to ako.

The difference is mostly in style:

• ako = the most common everyday word for if
• ukoliko = a bit more formal, administrative, or written

• Ako PIN ne radi, pozovite banku.
• Ukoliko PIN ne radi, pozovite banku.

Both are correct, but ukoliko sounds especially natural in instructions, notices, customer-service messages, and official writing.

Why does radi mean works? Doesn’t raditi usually mean to work as in having a job?

Yes, raditi can mean to work in the sense of doing a job, but it also very often means to function / to operate.

So PIN ne radi literally means:

• the PIN is not working
• the PIN does not function

This is very natural Serbian.

Some examples:

• Telefon ne radi. = The phone isn’t working.
• Internet ne radi. = The internet isn’t working.
• Kartica ne radi. = The card isn’t working.

So in this sentence, radi is not about employment. It means functions.
