Hot-headed peasants roughly grabbing one with nothing (10)
I believe the answer is:
passionate
'hot-headed' is the definition.
(hot-headed can mean full of passion or anger)
'peasants roughly grabbing one with nothing' is the wordplay.
'roughly' indicates anagramming the letters.
'grabbing' indicates putting letters inside.
'one' becomes 'i' (Roman numeral).
'with' means one lot of letters go next to another.
'nothing' becomes 'O' (looks like zero - 0).
'peasants' is an anagram of 'passnate'.
'i'+'o'='io'
'passnate' enclosing 'io' is 'PASSIONATE'.
(Other definitions for passionate that I've seen before include "Showing strong emotions" , "Most eager" , "Very keen" , "Strongly emotional" , "Showing intense feeling" .)
