Surrounded by many that will help out (4)
I believe the answer is:
amid
'surrounded by' is the definition.
(amid means among or surrounded by)
'many that will help out' is the wordplay.
I cannot quite see how this works, but
'many' could be 'm' (Roman numeral for a thousand) and 'm' is present in the answer.
'help' could be 'aid' (synonyms) and 'aid' is located in the leftover letters.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for amid that I've seen before include "Maid (anag)" , "In the thick of" , "Among" , "Amongst" , "In the course of" .)
