I have the following:

Sometimes it's hard to tell one twin from another.

I've already looked up in doferent resources, but I'm still not sure about it's meaning.

I don't know whether it is "to distinguish one from another" or "tell both the first and the second twin". Translator says it's the second option whereas I found information confirming the first meaning.

From the Oxford Advanced Learner's Dictionary

to distinguish one thing or person from another

  • tell something  It was hard to tell the difference between the two versions.
  • tell A from B  Can you tell Tom from his twin brother?
  • tell A and B apart  It's difficult to tell them apart.
  • tell which, what, etc…  The kittens look exactly alike—how can you tell which is which?
