One's art without frames, extremely versatile and daring (5)
I believe the answer is:
nerve
'daring' is the definition.
(I've seen this in another clue)
'one's art without frames extremely versatile' is the wordplay.
'one's' becomes 'ne' (I can't justify this - if you can you should give a lot more credence to this answer).
'without frames' indicates the central letters (remove the edge letters which 'frame' the words).
'extremely' suggests removing the centre (only the extremes of the word are used).
The middle of 'art' is 'r'.
'versatile' with its centre removed is 've'.
'ne'+'r'+'ve'='NERVE'
'and' acts as a link.
Can you help me to learn more?
(Other definitions for nerve that I've seen before include "displaying self-possession" , "Temerity" , "Bundle of fibres < in face" , "Cceek or courage" , "Sauce" .)
