Kielinäkymä
Äidinkielelläsi
In basic English clauses, the actor is usually before the verb and can trigger subject-verb agreement.
She opened the door.
she = the actor/source
Opiskeltavalla kielelläsi
The actor is often recoverable from verb agreement, so subject pronouns are frequently omitted unless needed for emphasis or contrast.
María prepara café.
María prepares coffee = María is the actor
Learners may overuse subject pronouns or miss that the verb ending already identifies the actor.
Same block, different coding
Both languages use this block strongly, but they signal it differently. Focus on form changes, not only meaning.
