English word order is rigid in a way Malayalam's isn't — and the reason why is the single most useful grammar fact on this page.
Grammar Comparison

Why Malayalam can reorder words and English can't
I ate rice. / *Rice ate I. (only one order is grammatical)
ഞാൻ ചോറ് കഴിച്ചു. / ചോറ് ഞാൻ കഴിച്ചു. (both orders are understandable)
Malayalam marks grammatical role with case suffixes, so the suffix — not the word order — tells you who did what to whom. That gives Malayalam freedom to reorder words for emphasis. English lost almost all of its case suffixes over the centuries, so it leans entirely on strict word order (subject, then verb, then object) to carry that same information. Moving the words in an English sentence doesn't just sound odd — it usually changes or destroys the meaning.
Articles: a genuinely new concept
a book / the book
പുസ്തകം — no article at all, in either case
Malayalam has no equivalent of 'a' or 'the' — a bare noun already works as either a specific or general reference, and context fills in the rest. English requires you to choose one of three options (a/an, the, or nothing) almost every time you use a noun, depending on things Malayalam never marks. This isn't a comparison so much as a warning: expect to make article mistakes for a long time, since Malayalam gives you no instinct to draw on here.
