Support some noncompliant Russians (5)
I believe the answer is:
truss
'support' is the definition.
(type of architectural support)
'some noncompliant russians' is the wordplay.
'some' indicates a hidden word (some of the parts of the word are used).
'TRUSS' is hidden within 'noncompliant russians'.
(Other definitions for truss that I've seen before include "US state" , "Frame supporting roof" , "Padded device worn to support a hernia" , "Surgical support" , "Type of support" .)
