formal

Kept secret or done secretively, especially because illicit.

While similar to 'covert,' 'clandestine' often carries a stronger implication of illegality, impropriety, or a deeper level of secrecy, often involving a sense of furtiveness or stealth to avoid detection.

The story behind the word. The word 'clandestine' has a wonderfully secretive past, coming directly from the Latin 'clandestinus,' which means 'secret, hidden.' This Latin root itself is thought to be related to 'clam,' meaning 'secretly,' and 'dies,' meaning 'day,' possibly hinting at something done 'away from the light of day.' It arrived in English in the mid-16th century, bringing with it a strong sense of illicit or furtive secrecy.
