After turning point, there's zero agitation (2-2)
I believe the answer is:
to-do
'agitation' is the definition.
(I've seen this before)
'after turning point there's zero' is the wordplay.
'after turning' is a reversal indicator.
'point there' becomes 'dot' (synonyms. I am not sure about the 'there' bit.).
'zero' becomes 'O' (O resembles 0).
'dot' in reverse letter order is 'tod'.
'tod'+'o'='TO-DO'
Can you help me to learn more?
(Other definitions for to-do that I've seen before include "Fuss and bother" , "Fuss or commotion" , "Quarrel" , "Kerfuffle" , "Spot of bother" .)
