Tinjauan bahasa
Dalam bahasa ibu Anda
Indonesian often uses topic-comment style without a separate topic marker.
Buku ini mahal.
This book expensive.
Dalam bahasa yang dipelajari
English has topic-comment patterns, but ordinary subject-verb-object order is more common than strong topic marking.
This book, I really enjoyed.
this book = the topic
Learners may copy topic-heavy structures from their native language and produce unnatural English word order.
Same block, different coding
Both languages use this block strongly, but they signal it differently. Focus on form changes, not only meaning.
