Corresponding without opening case for source (7)
I believe the answer is:
elative
'case for source' is the definition.
'elative' can be an answer for 'case' (thesaurus). I'm not certain of the 'for source' bit.
I can't explain the rest of the clue.
Can you help me to learn more?
I've seen this clue in The Times and The Sunday Times.
Want a hint initially instead of a full solution?
