One inflexible pole and feather duster? (8)
I believe the answer is:
stickler
'one inflexible' is the definition.
I can't judge whether this definition defines the answer.
'pole and feather duster?' is the wordplay.
'pole' becomes 's' (abbreviation for South, as in South Pole).
'and' means one lot of letters go next to another.
'feather duster?' becomes 'tickler'.
's'+'tickler'='STICKLER'
Can you help me to learn more?
(Other definitions for stickler that I've seen before include "Nit-picker" , "Pernickety person" , "Perfectionist" , "Person who insists as on protocol" , "Trickles for someone who insists" .)
