Frank's university (4)
I believe the answer is:
open
This clue might be a double definition.
'frank's' is the first definition.
(synonyms)
'university' is the second definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.
Can you help me to learn more?
(Other definitions for open that I've seen before include "Unfasten" , "This championship includes both professional and amateur golfers" , "Traditional room heater" , "Frank - unsettled" , "begin to > crack" .)
