It might help with a break in Adriatic resort around November (6)
I believe the answer is:
splint
'it might help with a break' is the definition.
The definition suggests a singular noun which matches the answer.
'adriatic resort around november' is the wordplay.
'adriatic resort' becomes 'split' (Croatian city).
'around' is an insertion indicator.
'november' becomes 'N' (phonetic alphabet: alpha, bravo, charlie etc.).
'split' going around 'n' is 'SPLINT'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for splint that I've seen before include "Bone setting support" , "Thin sliver of wood" , "Rigid material used to secure broken bone" , "Orthopaedic device for immobilising part of the body" , "strip of wood" .)
