What does detaining mean?
Detaining is the present participle of the verb 'detain,' meaning to keep someone in custody or under restraint, typically by an authority such as the police, immigration officials, or the military. It can also mean more mildly to delay someone from going where they need to be. The word is most prominent in legal and news contexts — people are described as being detained at borders, during investigations, or without charge, a phrase that often signals controversy over civil liberties. In everyday speech, using 'detaining' to mean simply holding someone up sounds slightly formal and is frequently framed as an apology: 'I'm sorry for detaining you.' The word derives from the Latin detinere, 'to hold away or keep back,' sharing its root with words like retain, contain, and tenant. Because of its association with lawful custody, 'detaining' carries a weightier connotation than mere 'stopping' or 'delaying' — it implies control exercised over another person, whether justified by law or not.

Etymology of detaining
Detaining comes from the Old French detenir, borrowed from the Latin detinere, formed from de- ('away, from') plus tenere ('to hold'), so the literal sense is 'to hold away or keep back.' The verb entered English in the late Middle Ages, with the senses of both lawful custody and simple delay developing early. Its root tenere also yields a wide family of English words, including retain, contain, tenant, tenure, and tenacious, all built on the idea of holding.
