Passage from one end of Salonica to the other? (4)
I believe the answer is:
stoa
'passage' is the definition.
(type of walkway or passage)
'one end of salonica to the other?' is the wordplay.
'one end of' means to remove the middle letters (I've seen 'ends of' mean this).
'the other?' indicates anagramming the letters (I've seen 'other' mean this).
'salonica' with its centre taken out is 'sa'.
'sa'+'to'='sato'
'sato' is an anagram of 'STOA'.
'from' is the link.
(Other definitions for stoa that I've seen before include "In Athens some columns" , "See Greek walk" , "Oast (anag.)" , "Greek portico or colonnade" , "Architectural feature" .)
