Questions & Answers about Suojaa pää, kun pakenet ulos.
How do we form the imperative suojaa from the Type 4 verb suojata?
For Type 4 verbs, you find the imperative by looking at the present tense minä (I) form. For suojata (to protect), the present tense is suojaan. Just drop the -n at the end, and you get the command suojaa (protect!).
Why is the object pää (head) in its basic dictionary form instead of having the -n ending?
Normally, a direct object takes the -n ending to show an action is being done to it. However, there is a special rule for commands: when the verb is an imperative like suojaa, its whole object drops the -n and looks exactly like the basic dictionary form.
Why is pakenet not in the imperative mood like suojaa?
The sentence is made of two different clauses joined by kun (when). The first part is a direct command to the listener (suojaa - protect!). The second part is a statement describing the situation when this should happen (pakenet - you flee). Therefore, pakenet stays in the normal present tense.
The English translation says "your head", but I don't see a word for "your" in Finnish. Why?
In Finnish, when you refer to body parts or clothing that clearly belong to the person doing the action, you usually don't need a possessive suffix or pronoun. Saying suojaa pää is perfectly natural, whereas translating it literally as suojaa sinun pääsi would sound a bit unnatural.
