In sea arrangement for Tuscan destination (5)
I believe the answer is:
siena
'tuscan destination' is the definition.
The definition suggests a singular noun which matches the answer.
'in sea arrangement' is the wordplay.
'arrangement' indicates an anagram.
'in'+'sea'='insea'
'insea' is an anagram of 'SIENA'.
'for' is the link.
Can you help me to learn more?
(Other definitions for siena that I've seen before include "Italian location" , "Walled city of Tuscany" , "somewhere in Italy)" , "Italian city strangely in sea" , "city in Italy" .)
