Mnemonic
Think: DE (undo) + CLASSIFY (put in a secret class) = to remove from a secret class. Like 'deactivate' a bomb, you 'declassify' a document.
Conceptual Metaphor
SECRECY IS A CONTAINER (to declassify is to open the container); INFORMATION IS A BURDEN (to declassify is to lift the burden of secrecy).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Not to be confused with 'рассекретить' (perfective) / 'рассекречивать' (imperfective) – the direct translation works well. Avoid using 'деклассировать', which means 'to downgrade in social class' and is a false friend.
Common Mistakes
- Incorrect: 'They declassified the secret.' (The secret *is* the information; better: 'They declassified the documents containing the secret.')
- Incorrect spelling: 'de-classify' (the hyphen is not standard in modern English).
