Learn Swedish: Sluta slåss och prata istället! - Stop fighting and talk instead!

It ends in an -s, but it's not a passive verb! Slåss is a reciprocal s-verb. It comes from the verb slå (to hit). When you add the -s to certain verbs, it implies an action done to one another—so "to hit each other" becomes "to fight". You'll see this same pattern in words like kramas (to hug each other) and ses (to see each other).

What verb forms are being used for sluta, slåss, and prata here?

Sluta (stop) and prata (talk) are both in the imperative (command) form, because you are giving the listener two direct instructions connected by och (and). However, slåss is in the infinitive form. It acts as the object of the first command—you are telling them to "stop [the action of fighting]".

Why isn't there an att (to) before slåss?

While you might logically expect sluta att slåss, it is standard in Swedish to drop the word att after verbs like sluta (to stop) and börja (to start) when referring to a general activity or habit. Just as you would say sluta röka (stop smoking), you say sluta slåss.

Could I say sluta bråka instead of sluta slåss?
