People chosen, European, in the Spanish court (5)
I believe the answer is:
elect
'people chosen' is the definition.
'elect' can be an answer for 'chosen' ('elect' as an adjective can mean chosen). I am not sure about the 'people' bit.
'european in the spanish court' is the wordplay.
'european' becomes 'e' (abbreviation e.g. EU).
'in' is an insertion indicator.
'the spanish' becomes 'el' ('the' in Spanish).
'court' becomes 'ct' (abbreviation used in road names).
'el'+'ct'='elct'
'e' put into 'elct' is 'ELECT'.
Can you help me to learn more?
(Other definitions for elect that I've seen before include "Choose; singled out" , "Waiting to get into office" , "Appoint through ballot" , "Preferred" , "Put in power by voting" .)
