Uninteresting version of a raid (4)
I believe the answer is:
arid
'uninteresting' is the definition.
(I've seen this in another clue)
'version of a raid' is the wordplay.
'version of' indicates an anagram.
'raid' with letters rearranged gives 'ARID'.
(Other definitions for arid that I've seen before include "Tedious; short of rain" , "Extremely dry" , "Wadi may be this" , "Dry raid" , "Dry, devoid of interest" .)
