Wandering mine, danger if exploded (10)
I believe the answer is:
meandering
'wandering' is the definition.
(I know that wandering can be written as meandering)
'mine danger if exploded' is the wordplay.
'if exploded' indicates anagramming the letters.
'mine'+'danger'='minedanger'
'minedanger' with letters rearranged gives 'MEANDERING'.
(Other definitions for meandering that I've seen before include "not proceeding directly" , "convoluted" , "Digressive" , "Tortuous" , "Serpentine?" .)
