Aaargh. That's British English. In the States we say "learned".
They should've learned America English, as there is no reference to the British nor the U.K. in this app !
"You learnt their songs." Why is it not accepted?
Probably just because they haven't added it ... or they're unaware that "learnt" is also correct.
How is it indicates that it's songs plural?
By zao. Nyimbo is in class 10, which takes the z- concord and "their" is -ao.
I thought it was the z- but ive also seen other words where it's not z-, its y-. How do we choose which prefix to use? (In general, too, for words not obviously of a particular consonant class)
You know some American dialects still say "I learnt it at class !" BUT . . . !
...that darn shur don't makit ok !
