You fellows round the ring will provide good farming stock (6)
I believe the answer is:
yeomen
'will provide good farming stock' is the definition.
I can't tell whether this definition defines the answer.
'you fellows round the ring' is the wordplay.
'you' becomes 'ye' (historical version of 'you').
'fellows' becomes 'men' (fellow can mean a man).
'round' is an insertion indicator.
'the ring' becomes 'o' (letter resembling a ring).
'ye'+'men'='yemen'
'yemen' placed around 'o' is 'YEOMEN'.
Can you help me to learn more?
(Other definitions for yeomen that I've seen before include "Ceremonial officers" , "Freeholders (historical)" , "Freeholders (hist.)" , "Monarch's ceremonial bodyguards" , "Sturdy old English folk" .)
