Send away eleven in the Spanish league, finally (5)
I believe the answer is:
exile
'send away' is the definition.
(I've seen this before)
'eleven in the spanish league finally' is the wordplay.
'eleven' becomes 'xi' (roman numeral).
'in' means one lot of letters goes inside another.
'the spanish' becomes 'el'.
'finally' says to take the final letters.
The last letter of 'league' is 'e'.
'xi' placed inside 'el' is 'exil'.
'exil'+'e'='EXILE'
(Other definitions for exile that I've seen before include "Overseas banishment" , "eg Napoleon on Elba" , "He is forced to live in another country" , "Ban to abroad" , "Person forced from country" .)
