Dispatched about one in ten with feeling (8)
I believe the answer is:
sentient
'with feeling' is the definition.
(I've seen this before)
'dispatched about one in ten' is the wordplay.
'dispatched' becomes 'sent' (I've seen this before).
'about' is an insertion indicator.
'one' becomes 'i' (Roman numeral).
'in' is an insertion indicator.
'i' put within 'ten' is 'tien'.
'sent' going around 'tien' is 'SENTIENT'.
(Other definitions for sentient that I've seen before include "Able to perceive/feel" , "Capable of feeling and perceiving things" , "Conscious - aware" , "Able to perceive or feel things" , "Feeling, conscious" .)
