Diphthong

A diphthong is two sounds pronounced together, usually in one syllable. A diphthong can have varying degrees of fusion, but in general it is two different sounds rather than one unblended sound. There is a diphthong in the Russian language, there is also a diphthong ai in English, and you can also find the diphthongs iu and I in it. Therefore, if we consider the question of whether it is worth distinguishing between a diphthong or not, of course yes, diphthongs have a place in the language because he makes it interesting, epic. In addition, diphthongs are good for conveying emotions, intonation, i.e. expressiveness.
