@moongold Maybe it's a subtle positive? It suggests to the child at an early age that words we use everyday are not always phonetic in the same way we potentially say the alphabet.
If you think about it, it's a staple in the English language.
I agree that it's random and frustrating sometimes, the feelings behind your post are genuine and understandable, but if the idea of letters having different pronunciations depending on words and context is set at an early age that is easier for the later education
Instead of being 5+ years old and being completely baffled, some letters aren't how you learned them.
Can you guarantee you'll only ever speak phonetically? It would be a struggle, and reading and teaching to read is gonna be a nightmare
