Certain characters in regatta individually win (6)
I believe the answer is:
attain
'win' is the definition.
(attain can mean to win or secure)
'certain characters in regatta individually' is the wordplay.
'ATTAIN' is hidden within the letters.
However, I'm uncertain how this is indicated.
Can you help me to learn more?
(Other definitions for attain that I've seen before include "Fulfil" , "Reach objective, get there" , "Gain with effort" , "Bring off" , "Succeed in reaching, achieve" .)
