"It is Monday today."
No - they messed up this question. It says понедідок is correct (it's not even a word)
Of course no :) д ≠ л
Maybe it's clearer when they are capitalized (Д ≠ Л)
I wondered about this - I have just come across the same л д error as you all
No. But д and л are next to each other, and is very easy to type wrong. I use Duo in the movil and the keyboard is very little. I appreciate that these mistakes are not considered ERRORs.
