Turned round, having a spot of bother (2-2)
I believe the answer is:
to-do
'bother' is the definition.
(I've seen this before)
'turned round having a spot' is the wordplay.
'turned' says the letters should be written in reverse.
'round' becomes 'o' (o is a circular letter).
'having' is a charade indicator (letters next to each other).
'a spot' becomes 'dot' (I've seen this before).
'o'+'dot'='odot'
'odot' written backwards gives 'TO-DO'.
'of' is the link.
(Other definitions for to-do that I've seen before include "Quarrel" , "Fuss or commotion" , "Spot of bother" , "Fuss and bother" , "Kerfuffle" .)
