A fellow Local Guide @Arum_Silviani replied one of my comments with this
“In Bandung, we said, “Haturnuhun”, a Sundanesse dialect 
”
How do you say thank you in your dialect?
Please specify the region and country!
I will go first, Igbos from South East Nigeria say “Imela”.
However, I live in Ilara-Mokin, Ondo State, Nigeria and they say “In sere”.
Hello @IfeanyiKOH
In Bangladesh, we say 'Dhonnobad’. In Bangla script ‘ধন্যবাদ’। Good to know Imela. 
Thank you.
Hello @IfeanyiKOH . In my Bengkulu dialect I would say “terimo kasih” which is very similar to bahasa Indonesia expression for “terima kasih”. For less formal I would say “trims”.
Nice topic!
In Tehran, Iran, we say “mamnoun”, “moteshakeram”, “merci” and the funnest one: “dastet dard nakoneh” which literally means “hope your hand doesn’t hurt”!!! Haha!
*Dhonnobad @SaifIS *
I’m glad to learn from you!
@AdriansyahPutera Is Bengkulu dialect spoken in Indonesia too?
Yes. Bengkulu dialect is one of 400’s dialects spoken in Indonesia. Bengkulu is a province located on Sumatra island and has about 4 million inhabitants. Imela @IfeanyiKOH .
Btw, how many dialects are spoken in Nigeria?
Really?! @AdriansyahPutera I think we share peculiarity in this regard because Nigeria is known to have well over 500 dialects. There’s in fact a region named Akoko in Ondo State where some neighbouring villages speak entirely different dialects. I hope to have you come visit Nigeria someday!
