Gushes about the Spanish guys! (7)
I believe the answer is:
fellows
'guys' is the definition.
(both can mean men)
'gushes about the spanish' is the wordplay.
'gushes' becomes 'flows' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'about' indicates putting letters inside.
'the spanish' becomes 'el' ('the' in Spanish).
'flows' going around 'el' is 'FELLOWS'.
Can you help me to learn more?
(Other definitions for fellows that I've seen before include "Companions" , "Chaps or associates" , "Members of college" .)
