Try hard at the end with skill to be accomplished pilot (7)
I believe the answer is:
earhart
'be accomplished pilot' is the definition.
The definition suggests a singular noun which matches the answer.
'try hard at the end with skill' is the wordplay.
'try hard' becomes 'ear' (I am not sure about this - if you are sure you should believe this answer much more).
'at the end' says to take the final letters.
'skill' becomes 'art' (both can mean a talent).
The final letter of 'with' is 'h'.
'ear'+'h'+'art'='EARHART'
'to' is the link.
Can you help me to learn more?
(Other definitions for earhart that I've seen before include "Amelia . . . . . . . , pioneer aviatrix" , "Amelia ....... was pioneering American aviator" , "Amelia ......, American pioneer aviator" , "Amelia __ , aviator, d. 1937" , "Flying ace" .)
