One in a row searched route out (8,5)
I believe the answer is:
terraced house
'one in a row' is the definition.
The definition suggests a singular noun which matches the answer.
'searched route out' is the wordplay.
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'searched'+'route'='searchedroute'
'searchedroute' is an anagram of 'TERRACED HOUSE'.
Can you help me to learn more?
(Other definitions for terraced house that I've seen before include "Dwelling in a row" , "Abode adjoined to others" , "Non-detached dwelling" .)
