Usage tips
Compound word
'Hausarrest' (house arrest) is a compound noun made up of 'Haus' (house) and 'Arrest' (arrest/detention). Here, 'Arrest' means 'Festhalten' (holding/detaining) or 'Einsperren' (locking up). So literally it is an 'Arrest im Haus' (arrest in the house).
EXAMPLE
Der Begriff bedeutet wörtlich, dass man als Strafe im Haus bleiben muss.
The term literally means that you have to stay in the house as a punishment.
Typical verbs
You can say 'Hausarrest haben' (to be grounded / to be under house arrest) or 'Hausarrest bekommen' (to get grounded / to get house arrest). If it is an official court order, the phrases 'unter Hausarrest stehen' (to be under house arrest) or 'jemanden unter Hausarrest stellen' (to place someone under house arrest) are more common.
EXAMPLE
Wenn du dein Zimmer nicht aufräumst, bekommst du eine Woche Hausarrest!
If you don't clean up your room, you'll be grounded for a week!
Context clue
You can tell from the context whether the punishment comes from parents or from a court. In a family setting, it is the parents who 'geben' (give) Hausarrest. In a legal context, it is authorities who 'unter Hausarrest stellen' (place someone under house arrest).
EXAMPLE
Meine Eltern haben mir Hausarrest gegeben, weil ich zu spät nach Hause kam.
My parents grounded me because I came home too late.

Hausarrest vs Haft
custody / imprisonment
'Haft' and 'Hausarrest' both have to do with a restriction of freedom. With 'Haft', a person is held by the police or justice system, often in prison or before a verdict. 'Hausarrest' means that someone is not allowed to leave their own apartment or house. This can be a punishment for children or a legal measure for adults. The words can be confused because both mean that someone cannot go freely. The place is the most important difference: 'Haft' is associated with prison or being held by the state, while 'Hausarrest' is associated with one's own home.
