Europeans go over a road in island (9)
I believe the answer is:
spaniards
'europeans' is the definition.
(people from Spain)
'go over a road in island' is the wordplay.
'go over' becomes 'span' (I've seen this in another clue).
'road' becomes 'rd' (abbreviation for road).
'in' indicates putting letters inside.
'island' becomes 'is' (abbreviation).
'a'+'rd'='ard'
'ard' placed inside 'is' is 'iards'.
'span'+'iards'='SPANIARDS'
(Other definitions for spaniards that I've seen before include "Natives of Seville, say" , "Pass dinar to Europeans" , "Iberians" .)
