Translation:The cat drinks water.
I thought it drinks tea.
I now have an image in my head of a cat throwing a tea party and tutting at the guests.
"The cat drinks the water" was rejected. Is it a missing translation or incorrect?
Missing translation. It is correct.
Cool, thanks for confirming!
Why is "cat drink water" not correct?
It's wrong English. You use 'drink' with 'I', 'you' and plural nouns/pronouns. For singular nouns and pronouns (except 'I' and 'you'), you use 'drinks'.
