Country where latest friend lost weight (5)
I believe the answer is:
nepal
'country' is the definition.
(Nepal is an example)
'latest friend lost weight' is the wordplay.
'latest' becomes 'new'.
'friend' becomes 'pal' (pal can mean a friend).
'lost' suggests deleting specific letters.
'weight' becomes 'w' (short for weight).
'new'+'pal'='newpal'
'newpal' with 'w' taken away is 'NEPAL'.
'where' is the link.
(Other definitions for nepal that I've seen before include "Hindu kingdom in south Asia" , "Small lake" , "former kingdom" , "Gurkha homeland" , "Asian republic" .)
