Then it's sealed - the Spanish one will bring writer to meet editor (8)
I believe the answer is:
unopened
'meet editor' is the definition.
Both the definition and answer are adjectives. Perhaps they are linked in a way I don't understand?
'then it's sealed the spanish one will bring writer' is the wordplay.
I cannot really see how this works, but
'sealed' could be 'unopen' (I've seen this in another clue) and 'unopen' is located in the answer.
'writer' could be 'ed' (I've seen this in other clues) and 'ed' is found within the answer.
This accounts for all the letters.
This explanation may well be incorrect...
'to' is the link.
Can you help me to learn more?
(Other definitions for unopened that I've seen before include "Having held onto seal" , "Remaining closed" , "shut" , "Still closed" , "Still sealed as post may be" .)
