Why is "the cow" correct, but not "a cow"?
Why is "a cow" not allowed?
It should be allowed, as far as I know.
the verb is an ending for a definite cow. if you use a cow then the verb will be 'piti hein'
That would be 'drinks milk' though?
Does cow have a different form for plural or could this be cows drink milk?
Cow doesn't, but it would be पिएँगी, with the ए suffix nasalised for plural (regardless of whether it's cows or something else, drinking or some other verb).
The word 'The' is compulsory here?
Yes, just as you said 'the word', it's needed for the same reason. Needs to be 'the cow', 'a cow', 'that cow', 'this cow', 'my cow', or something, not just 'cow' - which cow?
The cow will drink the milk was marked wrong.
The cow is gives us milk
Then how is cow drink milk
When is the future ending येगा used and when is the ending एगा used
The 'य्' is inserted by some speakers just as a pronunciation aid, a 'helper consonant' it's sometimes described as, just to make the double vowel less awkward.
Why the 'the cow' and not just 'cow'
"Cow will drink milk" is bad English. It has to be either "A cow" or "The cow".
Cow will drink the milk??
You need to say which cow in English - 'The cow', 'A cow', 'That cow', 'This cow', 'Your cow', 'My cow' , 'Cows [generally]', etc.
