Mother country at bottom of English issue (9)
I believe the answer is:
emanation
'issue' is the definition.
(I've seen this before)
'mother country at bottom of english' is the wordplay.
'mother' becomes 'ma' (ma can mean mother).
'country' becomes 'nation' (synonyms).
'at bottom of' says to put letters next to each other (in a down clue, some letters go underneath others).
'english' becomes 'E' (abbreviation).
'ma'+'nation'='manation'
'manation' after 'e' is 'EMANATION'.
(Other definitions for emanation that I've seen before include "Something given off" , "Something flowing out from a source" , "produce radioactive gas" , "Pouring out" , "Something produced from a source" .)
