Suffer again, cursing inwardly (5)
I believe the answer is:
incur
'suffer' is the definition.
(to incur is to suffer or experience)
'again cursing inwardly' is the wordplay.
'INCUR' is hidden in amongst the letters.
But, I'm unsure how the hidden word is indicated.
Can you help me to learn more?
(Other definitions for incur that I've seen before include "Become liable to (eg, a penalty)" , "Take on (obligation)" , "Become subject to (something unwelcome)" , "To become liable to, suffer" , "Become responsible for" .)
