Support a government with a spread of information (10)
I believe the answer is:
propaganda
'spread of information' is the definition.
'propaganda' can be an answer for 'information' (propaganda is a kind of information). I am not certain of the 'spread of' bit.
'support a government with a' is the wordplay.
'support' becomes 'prop' (prop up can mean to support).
'government' becomes 'g' (abbreviation for government).
'with' becomes 'and'.
'prop'+'a'+'g'+'and'+'a'='PROPAGANDA'
Can you help me to learn more?
(Other definitions for propaganda that I've seen before include "'Spin'" , "Hype" , "Dissemination of information" , "organised spread of information" , "publicity material" .)
