Insect, for example, slow, rising? (5)
I believe the answer is:
midge
'insect' is the definition.
(midge is a kind of insect)
'example slow rising?' is the wordplay.
'example' becomes 'eg'.
'slow' becomes 'dim' ('dim' can be a synonym of 'slow').
'rising?' says the letters should be written in reverse (going up in a down clue).
'eg'+'dim'='egdim'
'egdim' reversed gives 'MIDGE'.
'for' acts as a link.
(Other definitions for midge that I've seen before include "Gnat" , "Small person" , "Minute mosquito-like fly" , "Small, gnat-like fly" , "Dipterous insect, in swarms by water" .)
