Reckless forward taking on defender, finally (9)
I believe the answer is:
imprudent
'reckless' is the definition.
(I've seen this before)
'forward taking on defender finally' is the wordplay.
'forward' becomes 'impudent' (similar in meaning).
'taking on' indicates putting letters inside.
'defender finally' becomes 'r' (I can't explain this - if you can you should believe this answer much more).
'impudent' going around 'r' is 'IMPRUDENT'.
Can you help me to learn more?
(Other definitions for imprudent that I've seen before include "Incautious" , "Lacking in good sense or caution" , "'making the wrong choices'?" , "Unwise" , "not wise" .)
