Energetic, like a team with ten players dismissed? (3-3)
I believe the answer is:
all-out
'energetic' is the definition.
Both the answer and definition are adjectives. Maybe there's a link between them I don't understand?
'a team with ten players dismissed?' is the wordplay.
I cannot quite see how this works, but
'a' is present in the answer.
'ten' could be 'lo' (resembles 10) and 'lo' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
'like' acts as a link.
(Other definitions for all-out that I've seen before include "Using every resource" , "Using maximum energy and speed - nobody left at home" , "Thorough-going" , "Nobody home, or using every possible speed" , "Complete" .)
