Reflexive verbs
Some verbs are reflexive, which means they need to have a reflexive pronoun as an object. To take the verb skyndar sig 'hurry' as an example, it will be like this:
Jag skyndar mig 'I am hurrying'
Du skyndar dig 'You are hurrying'
Han/hon/hen/den/det skyndar sig 'He/she/it is hurrying'
Vi skyndar oss 'We are hurrying'
Ni skyndar er 'You are hurrying'
De skyndar sig 'They are hurrying'
Some verbs can be either reflexive or not reflexive, but take a normal object instead when they're not reflexive. For instance, the Swedish verb lär – either you learn 'yourself', or you teach someone else:
Jag lär mig svenska 'I am learning Swedish'
Du lär dig svenska 'You are learning Swedish'
etc, or:
Jag lär dig svenska 'I am teaching you Swedish'
Du lär mig svenska 'You are teaching me Swedish' etc.
