Region of the town that provides a capital start to the holiday
I believe the answer is:
parish
'region of the town that' is the definition.
'parish' can be an answer for 'region' (parish is a kind of region). I am unsure of the remainder of the definition.
'a capital start to the holiday' is the wordplay.
'a capital' becomes 'Paris' (Paris is the capital of France).
'start to' suggests taking the first letters.
The initial letter of 'holiday' is 'h'.
'paris'+'h'='PARISH'
'provides' is the link.
Can you help me to learn more?
(Other definitions for parish that I've seen before include "Rector's responsibility" , "Ecclesiastical district" , "District with own church and clergyman" , "Administrative area within a diocese" , "administrative district" .)
