Arrogant high-flier gets a rise to begin with (7)
I believe the answer is:
upstart
'arrogant high-flier' is the definition.
The definition suggests a singular noun which matches the answer.
'a rise to begin with' is the wordplay.
'a rise' becomes 'up' (as a noun).
'to' is a charade indicator (letters next to each other).
'begin with' becomes 'start' (synonyms. I am not sure about the 'with' bit.).
'up'+'start'='UPSTART'
'gets' acts as a link.
Can you help me to learn more?
(Other definitions for upstart that I've seen before include "Unexpectedly fresh" , "Recent promotees, say, behaving with arrogance" , "One who has risen suddenly to high position, and is arrogant with it" , "Arriviste, parvenu" , "Over-assertive newcomer" .)
