Dodge as David turns on English (5)
I believe the answer is:
evade
'dodge' is the definition.
(I know that dodge can be written as evade)
'david turns on english' is the wordplay.
'david' becomes 'dave' (Dave is short for David).
'turns' shows that the letters should be reversed in order.
'on' says to put letters next to each other.
'english' becomes 'e' (abbreviation).
'dave' in reverse letter order is 'evad'.
'evad'+'e'='EVADE'
'as' is the link.
(Other definitions for evade that I've seen before include "Hedge" , "temptress conveying commercial message" , "To get away from" , "Dodge - prevaricate" , "Illegally escape (taxes)" .)
