Was triumphant tailor seduced outside church? (9)
I believe the answer is:
succeeded
'was triumphant' is the definition.
I can't tell whether this definition defines the answer.
'tailor seduced outside church?' is the wordplay.
'tailor' indicates anagramming the letters (letters tailored or designed).
'outside' means one lot of letters goes inside another (some letters go outside others).
'church?' becomes 'CE' (abbreviation for Church of England).
'seduced' anagrammed gives 'suceded'.
'suceded' enclosing 'ce' is 'SUCCEEDED'.
Can you help me to learn more?
(Another definition for succeeded that I've seen is " Came into a title".)
