What does detained mean?
Detained is the past tense of the verb detain, meaning to keep someone in official custody or to delay them from going where they intended. Its most prominent modern use is legal and administrative: police detain suspects, immigration authorities detain travelers, and governments may detain people without formal charges, which is why the word often appears in news reporting about arrests and human rights. A second, milder sense simply means delayed — as in politely apologizing for being late because one was "detained" by business — though this usage now sounds somewhat formal or old-fashioned. The word comes from the Old French detenir and ultimately the Latin detinere, "to hold back," built on tenere, "to hold." That root also gives English retain, contain, and obtain, making detained part of a large family of words all concerned with holding something in place.

From the Latin tenere, "to hold," the same root that gives us "tenant" and "contain" — detained is literally what happens when authority decides you're not going anywhere.

Etymology of detained
Detained derives from Middle French detenir, from Latin detinere, meaning "to hold off" or "to keep back," formed from de- plus tenere, "to hold." The same Latin root underlies retain, contain, obtain, and tenacious, all entering English through French or directly. The word has been used in English since roughly the late 15th century, with its legal sense of keeping someone in custody well established by early modern times.
