Edges back to front through something resembling grass (5)
I believe the answer is:
sedge
'grass' is the definition.
(I've seen this before)
'edges back to front through something' is the wordplay.
'edges' can be anagrammed to 'SEDGE'.
But, I am not sure how the anagram is indicated.
'resembling' acts as a link.
Can you help me to learn more?
(Other definitions for sedge that I've seen before include "Grass-like plant growing in marshes" , "fly by rivers" , "Waterside plant" , "Plant like grass" , "water-loving vegetation" .)
