My prononciations of numbers are permanently not recognized.
Phonology question: Can anyone confirm my suspicion that the ь (мягкий знак) in пятьдесят is "silent", and has no bearing on the modern pronunciation? I can't see how to "palatalize" the т when it's followed by another alveolar stop, д.
My prononciation of numbers is never accepted by DL! What's wrong???
Can this not be fifty five years old or does it require a pronoun?
It could be, but only with additional context (e.g. if someone asked you "Сколько тебе лет?" and you omitted "мне" in the response). By itself it's just "fifty-five years," no more, no less.
This lesson is eternal.. It only gives you one point for twenty questions!
