Where there are hills and maybe snow at Land's End (5)
I believe the answer is:
downs
'where there are hills' is the definition.
The definition suggests a singular noun but the answer is a plural noun.
'maybe snow at land's end' is the wordplay.
'maybe' indicates anagramming the letters.
'at' is a charade indicator (letters next to each other) (I've seen this in other clues).
'end' indicates one should take the final letters.
The final letter of 'land' is 'd'.
'snow' with letters rearranged gives 'owns'.
'owns' put after 'd' is 'DOWNS'.
'and' is the link.
Can you help me to learn more?
(Other definitions for downs that I've seen before include "Southern uplands" , "S. England chalk hills" , "Gently rolling hills" , "Drinks in one" , "Knocks over; drinks" .)
