Holy area in southeastern Spain (3)
I believe the answer is:
see
'holy area' is the definition.
'see' can be an answer for 'area' (see is a kind of area). I am not certain of the 'holy' bit.
'in southeastern spain' is the wordplay.
'in' means one lot of letters goes inside another.
'southeastern' becomes 'SE'.
'spain' becomes 'e' (abbreviation for Espana).
'se' enclosing 'e' is 'SEE'.
Can you help me to learn more?
(Other definitions for see that I've seen before include "Get < court < witness" , "Consider; diocese" , "Perceive, watch" , "Bishop's diocese" , "Witness; ensure" .)
