I told myself, that I wont fall for the "you will have to use google for reading this trap"... (Mä and "google" gave you away, together with fact that last line was wishes.) then I felt that I might be wrong after all and checked. You got me.
I fell in love in cyphers (besides girlfriend and coins) so I now wish to have enough free time to learn Ogham https://en.wikipedia.org/wiki/Ogham
But basics of Finnish would be awesome too. Ok, I stole the thread.
I learned Russian so understand main topic, and Jarcek reply too - Czech is very simmilar to polish :)
Maybe one day will learn some ancient language it will be fantastic.
PS.
I even create my own alfabet it was i think 15 years ago :)
I know only some basics of Slavic languages but Russian contains many loan words which makes it actually easier to read than one would initially expect. I learned Latin and some Greek at grammar school, never liked Swedish but still easy to read and understand, speak better German instead and learned Dutch when moving there. My French could be better but thanks to Latin and some travels I can read Portuguese, Spanish, Italian and Romanian fairly well. Basic Estonian is pretty easy to read for a Finn as well. Hungarian on the other hand is too Ugric for a Balto-Finnic. Only a few words look familiar. Anyway, all useful when preparing these world coin chats.
Ogham looks great! I should write Finnish in Ogham!
