Romanian dictator stops hoarding uranium and copper (9)
I believe the answer is:
ceausescu
'romanian dictator' is the definition.
The definition suggests a singular noun which matches the answer.
'stops hoarding uranium and copper' is the wordplay.
'stops' becomes 'ceases' ('cease' can be a synonym of 'stop').
'hoarding' is an insertion indicator.
'uranium' becomes 'U' (U is the chemical symbol for uranium).
'and' says to put letters next to each other.
'copper' becomes 'Cu' (chemical symbol).
'ceases' enclosing 'u' is 'ceauses'.
'ceauses'+'cu'='CEAUSESCU'
Can you help me to learn more?
(Other definitions for ceausescu that I've seen before include "Repressive president" , "Communist president deposed and shot in 1989" , "Deposed Romanian leader" , "Romanian Communist leader, killed 1989" .)
