Reportedly obstruct some nations (4)
I believe the answer is:
bloc
'reportedly obstruct some nations' is the definition.
I can't tell whether this defines the answer.
'reportedly obstruct' is the wordplay.
'reportedly' shows a homophone (sound like).
'obstruct' becomes 'block' (synonyms).
'block' is a homophone of 'BLOC'.
Can you help me to learn more?
(Other definitions for bloc that I've seen before include "united nations" , "League" , "Combination of nations" , "Alliance of nations" , "Group acting together" .)
