I follow the Spanish priest (3)
I believe the answer is:
eli
'priest' is the definition.
(biblical figure)
'i follow the spanish' is the wordplay.
'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 "Old Testament priest, the prophet Samuel's teacher" , "OT high priest" , "Man" , "High priest in the Book of Samuel" , "- Whitney invented the cotton gin in seventeen ninety three" .)
