I will follow the Spanish patriarch (3)
I believe the answer is:
eli
'patriarch' is the definition.
(I've seen this before)
'i will follow the spanish' is the wordplay.
'will follow' means one lot of letters go next to another.
'the spanish' becomes 'el' ('the' in Spanish).
'i' after 'el' is 'ELI'.
(Other definitions for eli that I've seen before include "Teacher of prophet Samuel" , "High priest in the Book of Samuel" , "Shiloh priest (Bible)" , "OT high priest" , "Religious character" .)
