Avoids the Spanish dues perhaps (6)
I believe the answer is:
eludes
'avoids' is the definition.
(eluding is a kind of avoiding)
'the spanish dues perhaps' is the wordplay.
'the spanish' becomes 'el' ('the' in Spanish).
'perhaps' indicates anagramming the letters.
'dues' with letters rearranged gives 'udes'.
'el'+'udes'='ELUDES'
(Other definitions for eludes that I've seen before include "Avoids, dodges" , "Escapes skilfully from, evades capture" , "Escapes skilfully from, avoids" , "Escapes, baffles" , "Dodges, stays away from" .)
