Team leader going after qualification, one with discretion (8)
I believe the answer is:
diplomat
'one with discretion' is the definition.
I can't judge whether this defines the answer.
'team leader going after qualification' is the wordplay.
'leader' indicates taking the first letters.
'going after' says to put letters next to each other.
'qualification' becomes 'diploma' (type of academic qualification).
The initial letter of 'team' is 't'.
't' after 'diploma' is 'DIPLOMAT'.
Can you help me to learn more?
(Other definitions for diplomat that I've seen before include "negotiator" , "tactful one" , "State envoy" , "Official representing a country abroad" , "eg Ambassador" .)
