Bit of a kip invites efforts (8)
I believe the answer is:
attempts
'efforts' is the definition.
('attempt' can be a synonym of 'effort')
'bit of a kip invites' is the wordplay.
'bit of a kip' becomes 'at' ('at' is part of 'kip').
'invites' becomes 'tempts' (tempting is a kind of inviting).
'at'+'tempts'='ATTEMPTS'
(Other definitions for attempts that I've seen before include "Makes efforts" , "Makes a stab at" , "Takes a shot" , "Efforts, endeavours" , "Endeavours, tries" .)
