I love the emotion of the speaker who recorded this sentence! I feel terrified that I haven't made her potatoes ;-D
Why is "I am eating potatoes" incorrect? I thought Ukrainian didn't have progressive tense.
Why is it singular in Ukrainian but plural in English? Is it always said in singular case in Ukrainian?
I think you just made a mistake, by not writing an article "a" before your singular "potato". If you do write it, there is no mistake
Short answer: картопля is a collective noun, can mean potatoes, but also a single potato depending on the context.
