Edison contemporary creates lakeside houses (5)
I believe the answer is:
tesla
'edison contemporary' is the definition.
(I've seen this in another clue)
'creates lakeside houses' is the wordplay.
'houses' says the answer is hidden in the clue (part of the clue houses the answer).
'TESLA' can be found hidden inside 'creates lakeside'.
(Other definitions for tesla that I've seen before include "Physics unit" , "SI unit; steal (anag.)" , "Unit of magnetic flux density" , "electrical unit" , "Inventor" .)
