Beat man for touching (7)
I believe the answer is:
tangent
'touching' is the definition.
(I've seen this before)
'beat man' is the wordplay.
'beat' becomes 'tan' (I've seen this before).
'man' becomes 'gent' (gent is a kind of man**).
'tan'+'gent'='TANGENT'
'for' is the link.
(Other definitions for tangent that I've seen before include "Line grazing another" , "At which one can go off" , "seen to be touching" , "What people often go off at!" , "line in mathematics" .)
