Roars from the Spanish fans outside (7)
I believe the answer is:
bellows
'roars' is the definition.
('bellow' can be a synonym of 'roar')
'the spanish fans outside' is the wordplay.
'the spanish' becomes 'el' ('the' in Spanish).
'fans' becomes 'blows' (I can't justify this - if you can you should believe this answer much more).
'outside' is an insertion indicator (some letters go outside others).
'el' placed into 'blows' is 'BELLOWS'.
'from' is the link.
Can you help me to learn more?
(Other definitions for bellows that I've seen before include "sings very loudly" , "shouts belligerently" , "Device that blows a strong current of air" , "Fire fanner for Boswell" , "Accordion part" .)
