Midlands city’s church masked spear (7)
I believe the answer is:
leister
'spear' is the definition.
(I've seen this before)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for leister that I've seen before include "Fishing spear with three prongs" , "long pointed object" , "Trident, spear" , "instrument to pierce fish" , "Salmon-spear" .)
