Urges some simple modification (6)
I believe the answer is:
impels
'urges some' is the definition.
'impels' can be an answer for 'urges' (I've seen this before). I am not sure about the 'some' bit.
'simple modification' is the wordplay.
'modification' indicates anagramming the letters.
'simple' is an anagram of 'IMPELS'.
Can you help me to learn more?
(Other definitions for impels that I've seen before include "Spurs" , "Drives or forces" , "Drives on in simple way" , "Urges or drives to do something" , "Urges forward" .)
