Rugby Union convention in the country? (7)
I believe the answer is:
rurally
'in the country?' is the definition.
(I've seen this before)
'rugby union convention' is the wordplay.
'rugby' becomes 'RU'.
'union convention' becomes 'rally' (I can't justify this - if you can you should believe this answer much more).
'ru'+'rally'='RURALLY'
Can you help me to learn more?
(Other definitions for rurally that I've seen before include "In country fashion" , "In a country manner" , "In the countryside" , "in the sticks?" , "country style" .)
