See cedar chopped in fall (8)
I believe the answer is:
decrease
'fall' is the definition.
(I know that fall can be written as decrease)
'see cedar chopped' is the wordplay.
'chopped' indicates an anagram (letters chopped or smashed up).
'see'+'cedar'='seecedar'
'seecedar' with letters rearranged gives 'DECREASE'.
'in' is the link.
(Other definitions for decrease that I've seen before include "Peter out" , "Go down" , "Plummet" , "Reduce in size" , "Weaken" .)
