Powerful hint ensemble has taken on board (7)
I believe the answer is:
intense
'taken on board' is the definition.
The answer and definition are different parts of speech. However, past participle verbs and adjectives sometimes define each other.
'powerful hint ensemble has' is the wordplay.
'has' indicates the answer is hidden within the clue.
'INTENSE' can be found hidden inside 'powerful hint ensemble'.
Can you help me to learn more?
(Other definitions for intense that I've seen before include "Set nine (anag.)" , "'Ardent, forceful (7)'" , "Strongly-felt" , "Excited" , "Acute, concentrated" .)
