Greek character who struggled in Spain? (3)
I believe the answer is:
eta
'greek character' is the definition.
(letter from the Greek alphabet)
'struggled in spain?' is the wordplay.
I cannot quite understand how this works, but
'spain?' could be 'e' (abbreviation for Espana) and 'e' is present in the answer.
The remaining letters 'ta' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
'who' acts as a link.
Can you help me to learn more?
(Other definitions for eta that I've seen before include "Something like 10 [RHO]" , "Letter from abroad" , "character abroad?" , "Letter of Greek alphabet" , "Militants" .)
