Californian can, maybe! (4,4)
I believe the answer is:
rest room
This clue might be a double definition.
'californian' is the first definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
'can maybe' is the second definition.
'rest room' can be an answer for 'can' (thesaurus). I am not certain of the 'maybe' bit.
Can you help me to learn more?
(Other definitions for rest room that I've seen before include "American can" , "Public toilet (US)" , "Lavatory" , "Comfort station" , "convenience?" .)
