Provides online jokes (6)
I believe the answer is:
equips
'provides' is the definition.
(equipping is a kind of providing)
'online jokes' is the wordplay.
'online' becomes 'e' (as in e-mail or e-commerce).
'jokes' becomes 'quips' (a quip is a witty remark).
'e'+'quips'='EQUIPS'
(Other definitions for equips that I've seen before include "Supplies" , "Provides with the necessary tools" .)
