Symbol featuring on top of English coin (9)
I believe the answer is:
sovereign
'coin' is the definition.
(thesaurus)
'symbol featuring on top of english' is the wordplay.
'symbol' becomes 'sign' (I've seen this before).
'featuring' means one lot of letters goes inside another.
'on top of' becomes 'over' (I've seen this before).
'english' becomes 'e' (abbreviation).
'over'+'e'='overe'
'sign' enclosing 'overe' is 'SOVEREIGN'.
(Other definitions for sovereign that I've seen before include "more than a prince" , "Head of state" , "Old gold coin" , "Supreme ruler" , "Monarch - old coin" .)
