I am not a native English speaker, but I am not sure if there is any difference between "this is an ordinary cat" and "this cat is ordinary". Can someone please outine the difference in Bahasa/English to that extent?
The difference is subtle, "this is an ordinary cat" describes -an animal- as being just a cat and "this cat is ordinary" describes -this cat- as being ordinary.
Duolingo need training. "this cat is ordinary" follows normal speech patterns. Should be correct.
This cat is fat This cat is skinny This cat is ordinary
Normal speech patterns.
