Bird apt to get upset about some errors (6)
I believe the answer is:
parrot
'bird' is the definition.
(I know this)
'apt to get upset about some errors' is the wordplay.
'apt to' becomes 'trap' (I can't explain this - if you can you should believe this answer much more).
'get upset' is a reversal indicator (I've seen 'getting upset' mean this).
'about' means one lot of letters goes inside another.
'some' says to take the centre.
The middle of 'errors' is 'ro'.
'trap' in reverse letter order is 'part'.
'part' going around 'ro' is 'PARROT'.
Can you help me to learn more?
(Other definitions for parrot that I've seen before include "Raptor (anag.)" , "Tropical bird, may talk" , "Spout" , "Sick as a -" , "Unintelligent imitator" .)
