Have to follow a girl somewhere in Jamaica (10)
I believe the answer is:
bridgetown
'somewhere in jamaica' is the definition.
The definition suggests a singular noun which matches the answer.
'have to follow a girl' is the wordplay.
'have' becomes 'own' (to have something is to own it).
'to follow' means one lot of letters go next to another.
'a girl' becomes 'bridget' ().
'own' after 'bridget' is 'BRIDGETOWN'.
Can you help me to learn more?
(Other definitions for bridgetown that I've seen before include "in Caribbean" , "capital" .)
