Bungled (7)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
botched
'bungled' is the definition.
(I know that bungled can be written as botched)
This is all the clue.
(Other definitions for botched that I've seen before include "Messed up" , "Made a bags of" , "Made a mess of, spoiled by clumsy work" .)
