Kielinäkymä
Sinun kielessäsi
Actors are often nominative and reflected in verb agreement; explicit subjects can be omitted when the verb is enough.
كتب الطالب الدرس.
The student wrote the lesson.
Opiskeltavassa kielessä
Actors usually come before the object and verb; subjects are often unmarked but verbs reflect person and respect level.
মেয়েটি গান গায়।
The girl sings.
Learners may rely only on word order and miss verb agreement or honorific form.
Same block, different coding
Both languages use this block strongly, but they signal it differently. Focus on form changes, not only meaning.
