Singers coming from Portugal to Spain (5)
I believe the answer is:
altos
'singers' is the definition.
(alto is a kind of singer)
'coming from portugal to spain' is the wordplay.
'coming from' indicates a hidden word.
'ALTOS' is hidden within 'portugal to spain'.
(Other definitions for altos that I've seen before include "Choir members" , "Lowest female singing voices" , "Females who sing in the lowest range" , "Highest male, lowest female, voices" , "High male or low female voices" .)
