Slips or sidles around (6)
I believe the answer is:
slides
'slips' is the definition.
('slide' can be a synonym of 'slip')
'sidles around' is the wordplay.
'around' indicates anagramming the letters.
'sidles' is an anagram of 'SLIDES'.
'or' acts as a link.
(Other definitions for slides that I've seen before include "Pieces of glass under the microscope" , "Pieces of glass for study of specimens" , "Sloping chutes in playgrounds" , "Sloping chutes in the playground" , "Slips, slithers" .)
