It's the only letter with two disconnected parts. How did this letter ы come about?

  • Sorry, you're wrong way about "the only letter with two disconnected parts". What about Й, so called "shortened И"? And wait, there is Ё, as "Е with 2 dots". Apr 4, 2019 at 13:18

    @YurySchkatula Those can be considered diacritics. Something very different and common across orthographies of many languages. Apr 4, 2019 at 13:26

The letter ы is a ligature of ъ and і.

In the past, these were both vowels (something like /ɤ̞/ and /i/) and ы was considered as some mixture of those two vowels.

    Modern (and even pre-1918) 'ъ' is very much disconnected from its roots. This link can provide some insight: 'Yer'.
