Do what Edison did in outlet (6)
I believe the answer is:
invent
'do what edison did' is the definition.
I can't tell whether this definition defines the answer.
'in outlet' is the wordplay.
'outlet' becomes 'vent' (a vent is an outlet or opening).
'in'+'vent'='INVENT'
Can you help me to learn more?
(Other definitions for invent that I've seen before include "Design something new, create by thought" , "Come up with" , "Cook up" , "Design for the first time" , "Make or design something original" .)
