Questions & Answers about Nappaa minut ensin, ja minä otan etupenkin!
Why is the object minut instead of minä, since nappaa is an imperative command?
This is the core exception you are learning! Normally, when you give a command like nappaa, a regular noun object loses its object ending and looks just like the nominative (e.g., Nappaa avain! - Grab the key!). However, personal pronouns are exceptions. They always keep their special accusative -t ending (minut, sinut, hänet) even in imperative, passive, and necessity sentences.
Why do the two total objects in this sentence (minut and etupenkin) have completely different endings?
Because the rules for objects depend on both the word type and the clause type. minut is a personal pronoun, which uses the unique -t ending as its total object marker regardless of the imperative verb. etupenkin is a regular noun. Because it is the total object of a standard active verb (otan), it takes the regular genitive-accusative -n ending.
Does the verb napata usually mean to pick someone up in a car?
Its literal meaning is to grab, to snatch, or to catch. However, in colloquial Finnish, napata is often used for picking someone up along the way, very similar to saying "grab me on your way" in English. If you want a more standard, neutral verb for fetching or picking someone up, you would use hakea.
Do we really need the word before , since the verb ending already tells us who is taking the seat?
