Standard of Spain or Malta (6)
I believe the answer is:
normal
'standard' is the definition.
(associated in meaning)
'of spain or malta' is the wordplay.
'of' indicates a hidden word.
'NORMAL' can be found hidden inside 'spain or malta'.
(Other definitions for normal that I've seen before include "Conforming to what is usual" , "Ordinary, standard" , "Standard; at right angles" , "'Usual, standard (6)'" , "Usual; at right angles" .)
