Urge one politician to take lecturer in employment (7)
I believe the answer is:
impulse
'urge' is the definition.
('impulse' can be a synonym of 'urge')
'one politician to take lecturer in employment' is the wordplay.
'one' becomes 'i' (Roman numeral).
'politician' becomes 'mp'.
'to take lecturer' becomes 'l' (I can't explain this - if you can you should believe this answer much more).
'in' indicates putting letters inside.
'employment' becomes 'use' ('use' can be a synonym of 'employment').
'l' placed into 'use' is 'ulse'.
'i'+'mp'+'ulse'='IMPULSE'
Can you help me to learn more?
(Other definitions for impulse that I've seen before include "Chew" , "A sudden inclination to act (7)" , "A push; whim" , "Sudden urge to do something" , "Sudden or instinctive desire" .)
