Of the people who start travelling to Bali, possibly? (6)
I believe the answer is:
tribal
'of the people' is the definition.
The definition suggests a singular noun but the answer is not.
'start travelling to bali possibly?' is the wordplay.
'start travelling' becomes 'tr' (I am not sure about this - if you are sure you should believe this answer much more).
'possibly?' indicates an anagram (I've seen 'possibly' mean this).
'bali' is an anagram of 'ibal'.
'tr'+'ibal'='TRIBAL'
'who' acts as a link.
Can you help me to learn more?
(Other definitions for tribal that I've seen before include "Belonging to social grouping" , "Like many primitive societies" , "concerning an ethnic group" , "Of racial group or clan" , "Relating to people related by blood" .)
