Arranges to find no-one clad like row of posts (9)
I believe the answer is:
colonnade
'row of posts' is the definition.
'colonnade' can be an answer for 'row' (I've seen this before). I am not certain of the 'of posts' bit.
'arranges to find no-one clad' is the wordplay.
'no-one clad' can be anagrammed to 'COLONNADE'.
However, I am not sure how the anagram is indicated.
'like' is the link.
Can you help me to learn more?
(Other definitions for colonnade that I've seen before include "supporters in a row" , "Collection of columns" , "Row of columns supporting a roof" , "Arcade" , "Row of evenly spaced pillars" .)
