At university with jerk, pretentious and vulgar (7)
I believe the answer is:
upstart
'pretentious and vulgar' is the definition.
I can't tell whether this definition defines the answer.
'at university with jerk' is the wordplay.
'at university' becomes 'up' (slang term meaning at university).
'with' says to put letters next to each other.
'jerk' becomes 'start' (I've seen this in another clue).
'up'+'start'='UPSTART'
Can you help me to learn more?
(Other definitions for upstart that I've seen before include "Arrogant newcomer" , "Person suddenly risen in world, and arrogant" , "Arriviste, parvenu" , "Arrogant and presumptuous person" , "Arrogant person new in high position" .)
