Last of crop seed’s run out: one must keep stocking up! (9)
I believe the answer is:
suspender
'one must keep stocking up' is the definition.
I can't judge whether this definition defines the answer.
'last of crop seed's run out' is the wordplay.
'last of' suggests the final letters.
'out' indicates an anagram (out can mean wrong or inaccurate).
The last letter of 'crop' is 'p'.
'p'+'seeds'+'run'='pseedsrun'
'pseedsrun' is an anagram of 'SUSPENDER'.
Can you help me to learn more?
(Other definitions for suspender that I've seen before include "Supporter" , "One responsible for hold-up" , "Stocking-holding strap" , "Strap to hold up a stocking" , "One that supports stocking" .)
