Yearning for past? In Angola it's unusual (9)
I believe the answer is:
nostalgia
'yearning for past?' is the definition.
'nostalgia' can be an answer for 'yearning' (I've seen this before). I also know that 'past' relates to this answer.
'angola it's unusual' is the wordplay.
'unusual' indicates an anagram.
'angola'+'its'='angolaits'
'angolaits' with letters rearranged gives 'NOSTALGIA'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for nostalgia that I've seen before include "Love for the past" , "That may bring on homesickness" , "Backward-looking sentiment" , "Attraction to the past" , "Wistfulness" .)
