He needs Mike actively involved (8)
I believe the answer is:
enmeshed
'involved' is the definition.
(thesaurus)
'he needs mike actively' is the wordplay.
I cannot quite understand how this works, but
'he' could be 'ed' (short for Edward) and 'ed' is found in the answer.
'mike' could be 'm' (phonetic alphabet: alpha, bravo, charlie etc.) and 'm' is located in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for enmeshed that I've seen before include "Tangled up, snarled in" , "All tangled up as in net" , "Caught (in problem or snare)" , "Caught in as in net" , "Trapped" .)
