Across time you will encounter people who you will develop relations with, either as a best friend, friend, loved one or as an enemy. People relations are really simple in Nepali. Sathi is also more common than mitra. Also, Nepali lacks girlfriend/ boyfriend/ best friend so I have written the closest possible translation.:
Relatives/ Kin = इष्टमित्र (istamitra)
Friendship = मित्रता (mitrataa)
Friend = साथी (sathi) / मित्र (mitra)
True Friend = असल मित्र (asal mitra)
Enemy = शत्रु (satru) / दुश्मन (dushman)
Good Friend = मिल्ने साथी (milne sathi)
Loved one (Romantic): प्रिये (priye)
Acquaintance = चिनेको (chineko) [literally ‘familiar’]
Unfamiliar/ Stranger = नचिनेको (nachineko)
Thingamajig = फलानो (phalano)
