Peg very good to Norman initially (5)
I believe the answer is:
piton
'peg very' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe you can see a link between them that I don't see?
'good to norman initially' is the wordplay.
'good' becomes 'pi' (old-fashioned term for pious).
'initially' says to take the initial letters.
The initial letter of 'norman' is 'n'.
'pi'+'to'+'n'='PITON'
Can you help me to learn more?
(Other definitions for piton that I've seen before include "something used when climbing" , "Spiked climbing aid" , "Kind of rope-supporting peg used in rock-climbing" , "something upwardly mobile type hammers home" , "Peg driven into rock as climbing support" .)
