A place that has to be in Los Angeles? (5)
I believe the answer is:
lhasa
'a place' is the definition.
The answer and definition can be both locations as well as being singular nouns.
Maybe there's an association between them I don't understand?
'has to be in los angeles?' is the wordplay.
'to be in' is an insertion indicator.
'los angeles?' becomes 'LA' (abbreviation).
'has' inserted into 'la' is 'LHASA'.
'that' is the link.
Can you help me to learn more?
(Other definitions for lhasa that I've seen before include "Group; stripe" , "The Forbidden City in Tibet" , "Luxembourg's a" , "Tibetan holy city" , "foreign capital" .)
