'english ground' is the definition.
I don't know anything about this answer so I can't tell whether this works.

'absurdly i study a welsh flag outside' is the wordplay.
'absurdly' is an anagram indicator (I've seen this in other clues).
'welsh' becomes 'w'.
'flag' becomes 'emblem' (I can't justify this - if you can you should give a lot more credence to this answer).
'outside' is an insertion indicator.
'w'+'emblem'='wemblem'
'i'+'study'+'a'='istudya'
'istudya' anagrammed gives 'ystadiu'.
'ystadiu' placed inside 'wemblem' is 'WEMBLEY STADIUM'.
