Diplomatic insult island caught on wiretap (8)
I believe the answer is:
discreet
'diplomatic' is the definition.
(I've seen this before)
'insult island caught on wiretap' is the wordplay.
I cannot really understand how this works, but
'insult' could be 'dis' (I've seen this in another clue) and 'dis' is found in the answer.
'caught' could be 'c' (cricket abbreviation) and 'c' is found within the answer.
'on' could be 're' ('on' can be mean 'with reference to') and 're' is located in the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for discreet that I've seen before include "Circumspect, considerate" , "Unobtrusive, circumspect" , "Careful in keeping a secret" , "Doesn't give away secrets - can be trusted" , "Careful not to attract attention" .)
