Draw a time-consuming flyer (7)
I believe the answer is:
attract
'draw' is the definition.
(I know that draw can be written as attract)
'a time-consuming flyer' is the wordplay.
'time' becomes 't' (abbreviation).
'consuming' is an insertion indicator (consume can mean to bring in or absorb).
'flyer' becomes 'tract' (tract can mean a piece of writing).
't' going into 'tract' is 'ttract'.
'a'+'ttract'='ATTRACT'
(Other definitions for attract that I've seen before include "Appeal to, draw towards" , "Behave like a magnet" , "to be appealing" , "Arouse interest of" , "Entrance" .)
