Ishara = eshara 

Same name, different spelling. Can also mean symbol/gesture etc etc in other languages like Sanskrit, Hindi and I’m sure it means other stuff in other languages I haven’t looked up

Like Katy = Katie

I was told by people who speak Arabic visiting London on holiday years ago that my name meant sign/signal and they proceeded to keep saying it to each other while laughing - I dunno why 🤷🏽‍♀️ looked it up and google and Chat GPT and it said they were right, but I don’t speak Arabic so I can’t say for sure, you may well be right 🫂 does it not have a meaning in Arabic?
