Below, to Blake (5)
I believe the answer is:
neath
'below to blake' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for neath that I've seen before include "Lower than - a town in West Glamorgan" , "not on top" , "Under, poetically" , "Town near Swansea" , "town in South Wales" .)
