I am sending deep hamper (6)
I believe the answer is:
impede
'hamper' is the definition.
(I know that hamper can be written as impede)
'i am sending deep' is the wordplay.
'i am' becomes 'I'm' (contraction).
'sending' indicates anagramming the letters (letters are sent to different positions).
'deep' is an anagram of 'pede'.
'im'+'pede'='IMPEDE'
(Other definitions for impede that I've seen before include "Hinder or hold up" , "Obstruct or thwart" , "Delay or obstruct" , "Hamper" , "Hinder, create obstacle" .)
