BasicsofEast SlavicCyrillicTo make further explanations shorter and easier, I need to explain you what are iotated and non-iotated vowels. Non-iotated vowels are normal letters for vowels. They only represent one sound and usually don't do anything special. Examples are letters "А" and "О" from Part 1. Iotated vowels can be read in two ways, depending on a letter's position in a word. If an iotated vowel follows a consonant, the consonant is softened (palatalized, to be precise) and followed by a vowel sound. If an iotated vowel does not follow a consonant (like at the beginning of a word, after some other vowel, or after non-letter signs "ь", "ъ", " ʼ "), it is read as [j] + a vowel sound. You can hear this combination in English words "union", "Universe" and "unique". In Ukrainian and Rusyn, "Е" is not an iotated vowel. In Russian and Belarusian, it is an iotated vowel. "І" is an exception: this letter is considered non-iotated (because it has an iotated counterpart "Ї"), but it softens a consonant it follows. Part 4ЕеІіАа Оо
