Look into bronze nail as a solution (5)
I believe the answer is:
talon
'nail as a solution' is the definition.
I can't tell whether this definition defines the answer.
'look into bronze' is the wordplay.
'look' becomes 'lo' (archaic exclamation meaning 'look!').
'into' is an insertion indicator.
'bronze' becomes 'tan' (both can mean to get a sun tan).
'lo' placed within 'tan' is 'TALON'.
Can you help me to learn more?
(Other definitions for talon that I've seen before include "Bird's claw" , "Part of hobby" , "one that grips" , "Sharp hooked claw" , "Large claw" .)
