Questions & Answers about Vino încoace, dacă vrei să mă ajuți!
Why is the command form vino instead of something like vine?
Could I say aici instead of încoace?
You can, and people will understand you, but încoace is much more natural here. While aici means a fixed location (here), încoace implies movement toward the speaker (this way or hither). Because vino is an action of moving towards someone, încoace is the perfect match.
Why do we need the word să before mă ajuți?
In English you say you want TO help, using the dictionary form of the verb. In Romanian, after verbs expressing a wish or desire like a vrea (to want), you use the connecting word să followed by the conjugated verb. It literally translates closer to: if you want that you help me.
