Cares for some land (5)
I believe the answer is:
acres
'some land' is the definition.
(acres measure land)
'cares' is the wordplay.
'cares' can be anagrammed to 'ACRES'.
But, I'm not clear how the anagram is indicated.
'for' is the link.
Can you help me to learn more?
(Other definitions for acres that I've seen before include "Cares about these measurements?" , "Areas of 4840 square yards" , "Extensive landed property (often rolling)" , "may burden landed folk" , "Units of area" .)
