Achieve, accomplish (6)
I believe the answer is:
attain
I believe this is a double definition.
'achieve' is the first definition.
(synonyms)
'accomplish' is the second definition.
(I know that accomplish can be written as attain)
(Other definitions for attain that I've seen before include "Arrive at, accomplish" , "Succeed in doing, get there" , "Reach, get there as with ambition" , "Bring off" , "Reach or achieve" .)
