Frantic, the race for amount of land (7)
I believe the answer is:
hectare
'amount of land' is the definition.
'hectare' can be an answer for 'land' (I've seen this before). I am not certain of the 'amount of' bit.
'frantic the race' is the wordplay.
'frantic' indicates anagramming the letters (I've seen this in other clues).
'the'+'race'='therace'
'therace' anagrammed gives 'HECTARE'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for hectare that I've seen before include "The race (anag) - unit of area" , "Teacher of metric land measure" , "Extent" , "Metric land area" , "Metric measure of area" .)
