Hello! There is some mistake here. Several times I try to pass this level, but all the time the result is the same, that the pronunciation is incorrect. Check, please. Thank you in advance!
When do we you an apostrophe before a vowel? Why do we use it in "дев'ять" but don't use in "десять"?
I was also curious about this, so I did a bit of research and found this which basically says it's about pronunciation. The apostrophe means you pronounce both letters completely rather than letting them run together.
Yes, apostrophe is used only after specific letters with some exceptions and is never used after certain letters like С for example
Roughly speaking, десять = [десьать], дев’ять = [девйать]
(of course it's wrong to spell like that, only for transcription)
Hear a difference:
Девять is Russian.
