Press one married for Spanish melody (9)
I believe the answer is:
importune
'press' is the definition.
(thesaurus)
'one married for spanish melody' is the wordplay.
'one' becomes 'i' (Roman numeral).
'married' becomes 'm' (abbreviation, e.g. in genealogy).
'for spanish' becomes 'por' (I can't justify this - if you can you should believe this answer much more).
'melody' becomes 'tune' (synonyms).
'i'+'m'+'por'+'tune'='IMPORTUNE'
Can you help me to learn more?
(Other definitions for importune that I've seen before include "Persistently request" , "Harrass with persistent requests" , "plague" , "badger" , "Harry" .)
