Okay, kiddo, let me try to explain it to you. So, the Coptic language is a very old language spoken by some people in Egypt. And just like how English has different accents and ways of pronouncing words, Coptic also has different ways of pronouncing words depending on where you are from or what time period you are talking about.
Recently, there have been some people who want to change the way Coptic is pronounced so that it is easier for everyone to understand and speak. They call this the Coptic pronunciation reform.
Imagine if you were reading a book and some of the words were spelled differently or pronounced differently than how you were used to hearing them. It might be confusing for you and make it harder to understand what you were reading. That's kind of how some people feel about the different ways Coptic is pronounced.
So, these people want to make some changes, like making sure that certain letters are always pronounced the same way or getting rid of some of the sounds that are no longer used. This will make it easier for everyone to read and speak Coptic.
Overall, the Coptic pronunciation reform is a way for people to make sure that everyone is speaking and understanding Coptic in a similar way. It's like trying to create a universal language that everyone can understand.
