Deprehension is a relatively uncommon word, and as such, there are not many synonyms for it. However, the concept of deprehension- which refers to a legal term that means the act of apprehending or seizing- can be more broadly expressed using a range of more commonly used words, such as arrest, capture, seizure, detention or incarceration. These words all relate to the concept of taking someone or something into custody, either as a result of criminal activity or for legal reasons. While deprehension itself may not be widely used, its synonyms are staples of legal and law enforcement language.
