Reduce the amount of seed to the acre! (8)
I believe the answer is:
decrease
'reduce the amount' is the definition.
'decrease' can be an answer for 'reduce' (I've seen this before). I'm not sure about the 'the amount' bit.
'of seed to the acre' is the wordplay.
'of' indicates anagramming the letters (the answer comes from or 'of' the letters).
'to' says to put letters next to each other (I've seen this in other clues).
'seed' put after 'acre' is 'acreseed'.
'acreseed' anagrammed gives 'DECREASE'.
Can you help me to learn more?
(Other definitions for decrease that I've seen before include "Contract" , "Deminish, lessen" , "Iron out the wrinkles" , "Smooth" , "Grow smaller or less" .)
