Harbour around Point - God knows where that is (6)
I believe the answer is:
heaven
'god knows where that is' is the definition.
'heaven' can be an answer for 'god' (thesaurus). I'm unsure of the remainder of the definition.
'harbour around point' is the wordplay.
'harbour' becomes 'haven' ('haven' can be a synonym of 'harbour').
'around' indicates putting letters inside.
'point' becomes 'e' (E is an example).
'haven' enclosing 'e' is 'HEAVEN'.
Can you help me to learn more?
(Other definitions for heaven that I've seen before include "Nirvana, paradise" , "Ideal place" , "State of happiness" , "State of bliss" , "Abode of the blessed" .)
