Shrink from Land's End, say (5)
I believe the answer is:
dread
'shrink from' is the definition.
(thesaurus)
'land's end say' is the wordplay.
'end' says to take the final letters.
'say' becomes 'read' (synonyms).
The last letter of 'land' is 'd'.
'd'+'read'='DREAD'
(Other definitions for dread that I've seen before include "Awe" , "Intense fear" , "Fearful expectation" , "Hairstyle" , "Terror" .)
