One masters politics degree needs time (8)
I believe the answer is:
diplomat
'one masters politics' is the definition.
(a diplomat is someone who has mastered politics)
'degree needs time' is the wordplay.
'degree' becomes 'diploma' (I've seen this before).
'needs time' becomes 't' (I am not sure about the 'needs' bit.**).
'diploma'+'t'='DIPLOMAT'
Can you help me to learn more?
(Other definitions for diplomat that I've seen before include "National representative abroad" , "tactful one" , "Official such as an ambassador" , "eg Ambassador" , "Limp toad (anag.)" .)
