Curved row of houses (8)
I believe the answer is:
crescent
'curved row of houses' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for crescent that I've seen before include "Shape of moon in first or last quarter" , "Muslim emblem" , "Young moon shape" , "Curved row of houses" , "Curved aspect of the moon" .)
