2d cope with wet ground to win National (8)
I believe the answer is:
twopence
'2d cope with wet ground to win national' is the definition.
I can't judge whether this definition defines the answer.
'cope with wet ground to win national' is the wordplay.
'with' says to put letters next to each other.
'ground' indicates an anagram ('grind' the letters into a new form).
'to win' means one lot of letters goes inside another (some letters win or obtain others).
'national' becomes 'n' (abbreviation listed in Chambers).
'cope' put after 'wet' is 'wetcope'.
'wetcope' is an anagram of 'twopece'.
'twopece' placed around 'n' is 'TWOPENCE'.
Can you help me to learn more?
(Other definitions for twopence that I've seen before include "Not much money" , "very little bread" , "bit of history" , "Low-value coin" , "Penny plain, - coloured" .)
