custody
This term carries a heavy weight of authority and control. It suggests a boundary—either a physical wall of a cell or a legal boundary of a court order—that separates the person in custody from the general public or their own autonomy. There is an inherent power imbalance where the custodian holds the keys, whether literally or legally.
Uncountable when referring to the general state of being detained or the legal concept of guardianship. Countable when referring to specific legal arrangements or separate instances of guardianship.
