This person, crazy to seize power, received information (5)
I believe the answer is:
input
'received information' is the definition.
'input' can be an answer for 'information' (input is a kind of information). I am not sure about the 'received' bit.
'this person crazy to seize power' is the wordplay.
'this person' becomes 'i'.
'crazy' becomes 'nut' (I've seen this before).
'to seize' is an insertion indicator.
'power' becomes 'p'.
'nut' placed around 'p' is 'nput'.
'i'+'nput'='INPUT'
Can you help me to learn more?
(Other definitions for input that I've seen before include "Contribution of work or information" , "Signal fed to equipment" , "Signal feeding a circuit" , "Simple, without artifice" , "Signal supplied to a device" .)
