Sidle with no point – lazy! (4)
I believe the answer is:
idle
'lazy' is the definition.
(similar in meaning)
'sidle with no point' is the wordplay.
'with no' is a deletion indicator.
'point' becomes 'S' (S is an example).
'sidle' with 's' taken out is 'IDLE'.
(Other definitions for idle that I've seen before include "goalless" , "'Lazy, not doing anything (4)'" , "Maybe Eric" , "Circus entertainer" , "Not in action or at work" .)
