Cross closer to turn (4)
I believe the answer is:
rood
'cross' is the definition.
(term for a crucifix)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for rood that I've seen before include "Crucifix - old unit of area" , "- Loft; - screen" , "Old land measure of quarter of an acre" , "Area equal to 40 square rods" , "Cross, crucifix" .)
