Lovely place, this port out East (6)
I believe the answer is:
heaven
'lovely place' is the definition.
'heaven' can be an answer for 'place' (I have seen 'Place of bliss' mean 'heaven' so perhaps 'place' could also mean 'heaven'). I am not certain of the 'lovely' bit.
'port out east' is the wordplay.
'port' becomes 'haven' (both can mean a place of safety).
'out' is an insertion indicator.
'east' becomes 'e' (abbreviation).
'haven' placed around 'e' is 'HEAVEN'.
'this' is the link.
Can you help me to learn more?
(Other definitions for heaven that I've seen before include "Ideal place" , "Place of supreme bliss" , "Paradise, utopia" , "Elysium, Nirvana" , "Nirvana, paradise" .)
