Coarse person turning dried grass over and over (5)
I believe the answer is:
yahoo
'coarse person' is the definition.
(a yahoo is a rude or noisy person)
'turning dried grass over and over' is the wordplay.
'turning' shows that the letters should be reversed in order.
'dried grass' becomes 'hay' (I've seen this in another clue).
'over' becomes 'o' (cricket abbreviation).
'and' says to put letters next to each other.
'over' becomes 'o' (cricket abbreviation).
'hay' written backwards gives 'yah'.
'yah'+'o'+'o'='YAHOO'
(Other definitions for yahoo that I've seen before include "Lout (in Gulliver's Travels)" , "Brutish animal species from Gulliver's Travels" , "Brutal lout" , "Rude or brutish person" , "Swift brute" .)
