Discover international organisation named orbiting body (7)
I believe the answer is:
unearth
'discover' is the definition.
(to unearth is to discover or find)
'international organisation named orbiting body' is the wordplay.
I cannot quite understand how this works, but
'international' could be 'un' (I've seen this in other clues) and 'un' is found within the answer.
The remaining letters 'earth' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for unearth that I've seen before include "Expose" , "Excavate, dig up" , "Disinter" , "Bring out of obscurity" , "Dig up - uncover" .)
