Lift paper found under man (4)
I believe the answer is:
heft
'lift' is the definition.
(hefting is a kind of lifting)
'paper found under man' is the wordplay.
'paper' becomes 'ft'.
'found under' says to put letters next to each other.
'man' becomes 'he' (**).
'ft' after 'he' is 'HEFT'.
(Other definitions for heft that I've seen before include "Try to determine weight by lifting" , "Feel the weight of" , "Lift, carry; influence" , "Lift or hold something to assess its weight" , "Lift in order to heave, say an axe" .)
