I shout about grit — not good — that in shoe, perhaps (8)
I believe the answer is:
irritant
'i shout about grit not good that in shoe perhaps' is the definition.
Both the answer and definition are adjectives. Maybe they are linked in a way I don't understand?
'i shout about grit not good' is the wordplay.
'shout' becomes 'rant' (I've seen this in other clues).
'about' is an insertion indicator.
'not' is a deletion indicator.
'good' becomes 'g' (abbreviation).
'grit' with 'g' taken out is 'rit'.
'rant' placed around 'rit' is 'rritant'.
'i'+'rritant'='IRRITANT'
Can you help me to learn more?
(Other definitions for irritant that I've seen before include "distraction" , "causing annoyance" , "Trouble" , "Source of continual annoyance" , "Cause of itch" .)
