Vista por língua
Na tua língua materna
Topics can be fronted or resumed with pronouns, especially in spoken Brazilian Portuguese.
Esse livro, eu já li.
This book, I already read.
Na tua língua de aprendizagem
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.
