Live to a high standard at Land's End (5)
I believe the answer is:
dwell
'live' is the definition.
(I know that live can be written as dwell)
'high standard at land's end' is the wordplay.
'high standard' becomes 'well' (I am not sure about this - if you are sure you should believe this answer much more).
'at' says to put letters next to each other (I've seen this in other clues).
'end' says to take the final letters.
The final letter of 'land' is 'd'.
'well' after 'd' is 'DWELL'.
'to a' is the link.
Can you help me to learn more?
(Other definitions for dwell that I've seen before include "Remain" , "Harp" , "stay" , "Reside - linger" , "Hang out" .)
