Sort of annual said to be Spanish (10)
I believe the answer is:
andalusian
'be spanish' is the definition.
(Andalucia is a part of Spain)
'sort of annual said' is the wordplay.
'sort of' is an anagram indicator.
'annual'+'said'='annualsaid'
'annualsaid' anagrammed gives 'ANDALUSIAN'.
'to' acts as a link.
(Other definitions for andalusian that I've seen before include "Chicken" , "Spanish" .)
