Angry with contemporary conflicting tendency (12)
I believe the answer is:
crosscurrent
'conflicting tendency' is the definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
'angry with contemporary' is the wordplay.
'angry' becomes 'cross' (I've seen this before).
'with' means one lot of letters go next to another.
'contemporary' becomes 'current' (similar in meaning).
'cross'+'current'='CROSSCURRENT'
Can you help me to learn more?
(Other definitions for crosscurrent that I've seen before include "A tendency in conflict with another" , "Conflicting flow" , "Flow at an angle to the main flow" .)
