Legendary hero and cave man (6)
I believe the answer is:
fingal
'legendary hero and cave' is the definition.
I know that 'cave' relates to this answer.
'man' is the wordplay.
I cannot quite see how this works, but
'man' could be 'gal' and 'gal' is located in the answer.
The remaining letters 'fin' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for fingal that I've seen before include "Caveman" , "His cave is on Staffa" , "Epic Scot" .)
