How do I know if it's plural? And why do they speak so fast? Is that really how they sound in their language?
If it was one egg, it would be "Ett ägg". And yes, native speakers tend to speak fast.
So, plural would just exclude the ett? Thanks. Crazy how fast they speak.
Yes, the ett-words that are the same in singular and plural indefinite will most often have the indefinite article ett if singular.
Is there an explanation to why they give "The boy has an eggs." as a correct solution?
A mistake when designing the sentences to be included. I removed it now. Thank you.
