Constrained by underwhelming leadership (4)
I believe the answer is:
helm
'leadership' is the definition.
(I know that helm is a type of leadership)
'constrained by underwhelming' is the wordplay.
'HELM' is hidden within the letters.
But, I am not sure how the hidden word is indicated.
Can you help me to learn more?
(Other definitions for helm that I've seen before include "Steersman's place" , "Ship's steering apparatus" , "Steer (a boat/ship)" , "Steer (a boat or ship)" , "part of boat near stern" .)
