A tribe in grand turmoil show fortitude (4,3,4,2)
I believe the answer is:
grin and bear it
'fortitude' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.
'a tribe in grand turmoil' is the wordplay.
'turmoil' indicates an anagram (I've seen this in other clues).
'a'+'tribe'+'in'+'grand'='atribeingrand'
'atribeingrand' with letters rearranged gives 'GRIN AND BEAR IT'.
'show' acts as a link.
Can you help me to learn more?
(Other definitions for grin and bear it that I've seen before include "Accept stoically" , "Endure misfortune stoically" , "Be stoical" , "Suffer hardship without complaint" , "like the Cheshire Cat carrying a message?" .)
