Succeed in recalling number in European employment (5)
I believe the answer is:
ensue
'succeed' is the definition.
(I've seen this before)
'recalling number in european employment' is the wordplay.
'recalling' says the letters should be written backwards.
'number' becomes 'n' (n can represent any number).
'in' indicates putting letters inside.
'european' becomes 'E' (abbreviation e.g. EU).
'employment' becomes 'use' (how something is used).
'e'+'use'='euse'
'n' going within 'euse' is 'eusne'.
'eusne' back-to-front is 'ENSUE'.
'in' acts as a link.
(Other definitions for ensue that I've seen before include "succeed" , "Occur afterwards" , "Happen afterwards as a result" , "Arise" , "Happen as a result, follow ( 5)" .)
