Having the means (4)
I believe the answer is:
able
'having the means' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for able that I've seen before include "Having the power, skill or means (to do something)" , "displaying skill" , "Bale out, being competent" , "Capable or proficient" , "Competent - sort of seaman" .)
