Volunteers to return pamphlet and draw (7)
I believe the answer is:
attract
'draw' is the definition.
(attracting is a kind of drawing)
'volunteers to return pamphlet' is the wordplay.
'volunteers' becomes 'TA' (abbreviation for Territorial Army).
'to return' says the letters should be written backwards.
'pamphlet' becomes 'tract' (synonyms).
'ta' in reverse letter order is 'at'.
'at'+'tract'='ATTRACT'
'and' acts as a link.
(Other definitions for attract that I've seen before include "Exercise a magnetic influence" , "to be appealing" , "Draw, pull" , "Appeal to, draw towards" , "Draw towards one, as magnet does metal" .)
