Superior person. The Spanish explosives expert (5)
I believe the answer is:
nobel
'explosives expert' is the definition.
The definition suggests a singular noun which matches the answer.
'superior person the spanish' is the wordplay.
'superior person' becomes 'nob' (I can't explain this - if you can you should believe this answer much more).
'the spanish' becomes 'el' ('the' in Spanish).
'nob'+'el'='NOBEL'
Can you help me to learn more?
(Other definitions for nobel that I've seen before include "and 21 Across: Prestigious international award" , "Source of prizes" , "Founder of many prizes" , "Swedish prize-giver" , "Alfred -, Swedish dynamite inventor" .)
