Maiden's help (3)
I believe the answer is:
aid
'maiden's help' is the definition.
'aid' can be an answer for 'help' (synonyms). I am unsure of the 'maiden's' bit.
'maiden's help' is the wordplay.
'help' indicates a hidden word (I've seen 'helping' mean this (a helping or portion of the letters)).
'AID' can be found hidden inside 'maidens'.
Can you help me to learn more?
(Other definitions for aid that I've seen before include "Help or support" , "charity" , "grant" , "assistant" , "Auxiliary" .)
