Sort out a point with an impatient utterance (5)
I believe the answer is:
snort
'an impatient utterance' is the definition.
'snort' can be an answer for 'utterance' (snort is a kind of utterance). I'm not certain of the 'an impatient' bit.
'sort out a point' is the wordplay.
'out' is an insertion indicator.
'a point' becomes 'n' (N is an example).
'sort' placed around 'n' is 'SNORT'.
'with' acts as a link.
Can you help me to learn more?
(Other definitions for snort that I've seen before include "Chortle" , "Derisive noise made through nose" , "Noisily express indignation" , "Force air out of the nose" , "Take illegal drug" .)
