It's near the cathedral (5)
I believe the answer is:
close
'it's near' is the definition.
(synonyms)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for close that I've seen before include "Near - shut" , "Near, mean or humid" , "Complete, a deal or case say" , "N ear; shut" , "cul-de-sac" .)
