Cycle around a bit: it's cloudless (5)
I believe the answer is:
clear
'cloudless' is the definition.
(thesaurus)
'cycle around a bit' is the wordplay.
'a bit' indicates a hidden word (the answer is formed by a bit of the clue).
'CLEAR' is hidden within 'cycle around'.
'it's' acts as a link.
(Other definitions for clear that I've seen before include "Bright" , "With no jams" , "Bold" , "Easily understood" , "Get net" .)
