Native American back in factory showing peevish impatience (8)
I believe the answer is:
petulant
'peevish impatience' is the definition.
(I've seen this before)
'native american back in factory' is the wordplay.
'native american' becomes 'ute' (I can't explain this - if you can you should believe this answer much more).
'back' says the letters should be written backwards.
'in' is an insertion indicator.
'factory' becomes 'plant' (I've seen this before).
'ute' back-to-front is 'etu'.
'etu' going into 'plant' is 'PETULANT'.
'showing' is the link.
Can you help me to learn more?
(Other definitions for petulant that I've seen before include "Easily provoked" , "peevish impatience" , "Sullen in a peevish way" , "Fractious, peevish" , "Pouting" .)
