Questions & Answers about Hae reipas koira sisään.
Why is the object reipas koira in the basic nominative form instead of reippaan koiran?
Because the verb hae is a command. Normally, a total object (meaning you are fetching the whole dog) would take the genitive -n ending. However, with imperative command verbs, the object drops this ending and looks exactly like the basic nominative form.
Since the noun drops its object ending, does the adjective have to drop it too?
Exactly! Adjectives always have to match the case of the noun they describe. Because the command rule makes koira drop its -n ending, the adjective reipas must do the same. In a normal statement like "I fetch the energetic dog", both would take the -n ending: Haen reippaan koiran.
How do we get the command hae from the dictionary verb?
The dictionary verb is hakea (to fetch). To make a basic command, you first find the "I" form. When you conjugate hakea to minä haen, the k disappears because of a rule called consonant gradation. Then, simply remove the -n from haen, leaving you with the command hae.
