Origin
From Latin clandestinus (secret, hidden), from clam (secretly).
History
Clandestine entered English for meetings, marriages and missions conducted out of sight. Journalism still favors it for covert operations and quiet deals. It is stronger than private and closer to concealed. The word implies intention: someone chose secrecy, not mere quiet.
