Condemn structure in speech (8)
I believe the answer is:
sentence
This clue could be a double definition.
'condemn' is the first definition.
(synonyms)
'structure in speech' is the second definition.
'sentence' can be an answer for 'structure' (sentence structure is a kind of structure). I am unsure of the 'in speech' bit.
Can you help me to learn more?
(Other definitions for sentence that I've seen before include "Bird, possibly" , "Group of words with verb" , "String of words or term in prison" , "It makes sense" , "The fate of criminals" .)
