Bitter criticism. I'd bear it somehow (8)
I believe the answer is:
diatribe
'bitter criticism' is the definition.
'diatribe' can be an answer for 'criticism' (I have seen 'Violent criticism' mean 'diatribe' so perhaps 'criticism' could also mean 'diatribe'). I'm not certain of the 'bitter' bit.
'i'd bear it somehow' is the wordplay.
'somehow' is an anagram indicator.
'id'+'bear'+'it'='idbearit'
'idbearit' is an anagram of 'DIATRIBE'.
Can you help me to learn more?
(Other definitions for diatribe that I've seen before include "Strong words" , "I debar it, being a violent attack in words" , "A Prolonged harangue" , "Lengthy harangue" , "Hostile rant" .)
