Also right! Her Majesty into bullfighter (6)
I believe the answer is:
torero
'bullfighter' is the definition.
(synonyms)
'also right her majesty into' is the wordplay.
'also' becomes 'too' (synonyms).
'right' becomes 'r' (common abbreviation).
'her majesty' becomes 'ER' (Elizabeth Regina).
'into' means one lot of letters goes inside another.
'r'+'er'='rer'
'too' placed around 'rer' is 'TORERO'.
(Other definitions for torero that I've seen before include "Escamillo, for example" , "One perhaps impaled" , "Bullring occupant" , "Blood-sport participant" , "Spanish fighter" .)
