Some foreign government (5)
I believe the answer is:
reign
'some foreign government' is the definition.
'reign' can be an answer for 'government' (thesaurus). I'm not sure about the 'some foreign' bit.
'some foreign government' is the wordplay.
'some' says the answer is hidden in the clue (some of the parts of the word are used).
'REIGN' can be found hidden inside 'foreign government'.
Can you help me to learn more?
(Other definitions for reign that I've seen before include "time in power" , "Time on throne" , "Monarch's time in the job" , "Period of a monarchy" , "Period during which someone is dominant" .)
