It's generally associated with appellation in ad, very oddly (8)
I believe the answer is:
vineyard
'it's generally associated with appellation' is the definition.
I know that 'appellation' relates to this answer.
'in ad very oddly' is the wordplay.
'oddly' indicates an anagram.
'in'+'ad'+'very'='inadvery'
'inadvery' anagrammed gives 'VINEYARD'.
Can you help me to learn more?
(Other definitions for vineyard that I've seen before include "Farm of grapes" , "Naboth's was an old" , "Grapes are grown here" , "Plantation of grape-bearing climbers" , "Place where grapes grow" .)
