Cyrillic alphabet and Latin
I've been trying to learn Russian for a couple of years, as an English speaker. I'm not very good at it yet but I adore it. First few months, I wasn't reading or typing much of anything in English. Just focused on learning Cyrillic alphabet, and the bemusing wonders of the Russian language.
Since mastering the alphabet, I find that in unknown English words - particularly acronyms, abbreviations - my brain came to default to Cyrillic. I would read the Englush/Latin letters as Russian sounds. This has only amused me, now having a dual alphabet brain.
Yesterday, however, I encountered a genuine problem 😄. I had an eye sight examination. Ages of reading wall charts with dozens of different lenses in, being asked to read the bottom two rows of letters. Being in England, the letter chart has Latin letters, and I have to read them aloud to show the optometrist any vision problems.
But all the letters that our two alphabets have in common, like P, H, but have different sounds, I kep getting wrong. Telling the optometrist I could see an N when actually it is an H. Telling him i see an R when actually it is a P. I struggled over every letter, working hard to try pronounce it in the requested English language.
Afraid i was going to end up with quite the wrong lens prescriptions, i had to explain my difficulties to the optometrist. I can read the letters correctly, with clear sight, but am pronouncing them wrong.
