Story of the letter G (6)
I believe the answer is:
legend
'story' is the definition.
(I know that legend is a type of story)
'letter g' is the wordplay.
I cannot quite see how this works, but
'letter' could be 'en' (I've seen this in other clues) and 'en' is located in the answer.
'g' is found in the answer.
The remaining letters 'led' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
'of the' is the link.
Can you help me to learn more?
(Other definitions for legend that I've seen before include "Myth or map symbol" , "Motto" , "eg Robin Hood" , "Stanley Matthews, perhaps" , "Person who has become famous" .)
