Thank you 😊🫶
The same way it's written, I think? Or however you like. I won't get into your head and scold you for pronouncing it one way and not the other haha
I pronounce it differently in my head each time I read it, lol. Oh-SAW-run, oh-SAY-ren, OH-sa-run, and oh-SEIR-rahn are some of the ways I've read it.
In my head it's like oh-sa-ROHN 🤔
