Frozen for example returning to top (5)
I believe the answer is:
gelid
'frozen' is the definition.
(thesaurus)
'example returning to top' is the wordplay.
'example' becomes 'eg'.
'returning' says the letters should be written backwards.
'to top' becomes 'lid' (lid is a kind of top).
'eg' back-to-front is 'ge'.
'ge'+'lid'='GELID'
'for' is the link.
(Other definitions for gelid that I've seen before include "Extremely cold, frozen" , "Glacial" , "Icy cold - glide (anag)" .)
