Minor point— in sentence building exercises, the first word of the sentence shouldn’t be written with a capital letter in the word box — this alerts the user that it’s definitely the first word. Of course some words must always be capitalized (proper nouns), but not elephants!
"Elephants eat large bananas" should be accepted as big and large are the same!
how to know when a noun needs an article (e.g the elephants) and when it does not?
They have it funky on here for grammar based on that, in Hindi it requires "एक (ek)" to use the article "a/an" and without "एक (ek)" it has an implied "the"
So "Big elephants eat bananas" would be: बड़े हाथी केले खाते हैं ?
The adjective always goes before the noun?
