Studied type of jazz while touring in Spain (7)
I believe the answer is:
trained
'studied' is the definition.
(training is a kind of studying)
'type of jazz while touring in spain' is the wordplay.
'type of jazz while' becomes 'trad' (I can't explain this - if you can you should believe this answer much more).
'touring' indicates putting letters inside (touring can mean going round).
'spain' becomes 'e' (abbreviation for Espana).
'in'+'e'='ine'
'trad' going around 'ine' is 'TRAINED'.
Can you help me to learn more?
(Other definitions for trained that I've seen before include "Prepared for race" , "I daren't (anag)" , "Worked out" , "Taught; exercised" , "Prepared for a task or career" .)
