Embarrassing as brought together, catching cutting remark, new (11)
I believe the answer is:
undignified
'embarrassing' is the definition.
(something undignified might be embarrassing)
'brought together catching cutting remark new' is the wordplay.
'brought together' becomes 'unified' (I've seen this before).
'catching' means one lot of letters goes inside another.
'cutting remark' becomes 'dig' (I've seen this before).
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'dig'+'n'='dign'
'unified' going around 'dign' is 'UNDIGNIFIED'.
'as' is the link.
(Other definitions for undignified that I've seen before include "Unseemly, looking foolish" , "Not becoming" .)
