How to say hello in Gujarati
Gujarati does not really have a word for hello. It has a question, કેમ છો, and a greeting reserved for elders. Getting the order right matters more than the pronunciation: with a grandmother you greet first and ask second.
The everyday hello
With elders, this comes first
In many Gujarati families, especially Vaishnav ones, elders are greeted with Jai Shri Krishna, hands folded, before anything else. Then kem chho. Mirror whatever the family says to you: it is the fastest way to get it right.
Introducing yourself
One trap for Hindi speakers: Gujarati has a third gender, neuter, and નામ naam is neuter. So it is maaru~ naam, not maaro.
The goodbye
આવજો literally means do come again, which tells you everything about how Gujarati families treat leaving. Both sides say it.
One thing to know
You will hear છે written and said as both chhe and che. Same word. The h is a breath, and how much of it you hear depends on the speaker and the region. Nobody will correct you either way.
