Theme
The theme is the displaced entity, the entity that moves. This does not have to be the subject.
Example:
Jeg dyttet skapet bortover.
“I pushed the closet”
| Jeg | 
| jeg | 
| I1SG | 
| N | 
| dyttet | |
| dytte | t |

| V | |
| skapet | |
| skap | et | 
| closet | theDEF | 
| N | |
| bortover | 
| bortover | 
| along | 
| ADVm | 
'Skapet' is here the displaced entity, even though it is not the subject.
'Jeg' is here the displaced entity, and also the subject of the sentence.
