Work out a cryptogram
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
decode
'work out a cryptogram' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for decode that I've seen before include "Get cracking" , "Convert a message into ordinary language" , "Interpret" , "Do translation" , "Explain" .)
