Maker of arrows -- one bringing round fifty (8)
I believe the answer is:
fletcher
'maker of arrows' is the definition.
(I've seen this before)
'one bringing round fifty' is the wordplay.
I cannot really understand how this works, but
'fifty' could be 'l' (Roman numeral) and 'l' is found in the answer.
The remaining letters 'fetcher' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for fletcher that I've seen before include "quarrel-maker?" , "Maybe Christian" , "Old playwright" , "One makes arrows" , "Manufacturer of bows and arrows" .)
