9. Imperative
The imperative is a form that expresses a command.
Depending on which verb group the verb belongs to, the imperative can be formed by using either the infinitive form or the stem of the verb. If the present tense ending of the verb is -ar, then the infinitive form is used. If the ending is either -er or -r, the ending is removed and the stem of the verb is used as the imperative instead.
Group 1: Stanna här! (stann/ar -> infinitive = imperative)
Group 2: Rök inte! (rök/er -> verb stem = imperative)
Group 3: Tro på mig! (tro/r -> verb stem = imperative)
Group 4: Ät bättre! (ät/er -> verb stem= imperative)
Rök inte!
