Studies to disregard almost, according to the despatcher (9)
I believe the answer is:
consignor
'disregard almost according to the despatcher' is the definition.
I can't tell whether this definition defines the answer.
'studies' is the wordplay.
I cannot quite see how this works, but
'studies' could be 'cons' (to con is to study or revise) and 'cons' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
'to' is the link.
Can you help me to learn more?
(Another definition for consignor that I've seen is " transmitter".)
