Uso means brother or sister. It's a bit complicated but I'll try my best to explain...
You would only call your sister your "uso" if youwere a girl.
You would only call your brother your "uso" if youwere a boy.
If you are a girl, you would refer to your brother as your "tuagane".
If you are a boy, you would refer to your sister as your "tuafafine".
Uso is a term used to refer to Samoans as a brother, whether they're related or not. Often used as a term of respect.
If you mean "uso", it's the same word for brother or sister.
It's Uso (ohh so)
uso = my brother
Thank you very much to you my brother/sister. Uso translates to both brother and sister in Samoan, depending on which gender you're interacting with.
Thank you brother = Faafetai lava uso.
"Ou te misia oe, lo'u uso" or "Ua ou misia oe, lo'u uso".
Uso-Cousin or family
Uso, Manuia le aso fanua
It gets a bit tricky so I'll try my best...Brother in Samoan is "uso"..but that's only if you're a male referring to his brother. A female would refer to her brother by calling him her "tuagane". A female would refer to her sister by calling her her "uso". Hope that helps.
Uso If you're a girl, then it is "uso". If you are boy, you would refer to your sister as a "tuafafine". (And if you are a girl, you would refer to your brother as your "tuagane") The word "uso" is also given used by a male when referring to his brother.
Sister is uso if a female is talking about her sister; tuafafine if a male is talking about his sister. Brother is uso if a male is talking about his brother; tuagane if a sister is talking about her brother. Cousin is Tausoga, so if it is a male cousin, it's tausoga-tama, and if it is a lady cousin, it's tausoga-teine.
If a female is talking, it's "uso"; if a brother is talking, it's "tuafafine".
