Questions & Answers about Buku ini tipis dan menarik.
Malay uses a noun–demonstrative order. The demonstrative ini (“this”) always follows the noun:
buku ini = “this book”
To say “that book,” swap ini for itu:
buku itu
The normal order in Malay is noun + adjective:
rumah besar (“big house”), buku tipis (“thin book”)
There are virtually no productive exceptions in everyday language. You might encounter reversed order in poetry or fixed expressions, but for learners the rule is: adjectives follow the noun.
