She's calling her friend.
I believe the term is "Beso su amiga" which means "He kissed his (girl)friend in Spanish. The word besos is plural for kiss = kisses.
You would say "Ella no es tu amiga." (or su amiga for the formal you, usted) If you mean 'She is not my friend' - "Ella no es mi amiga".
Your friend (in a respect tone) His/her female friend (if talking about other person)
Your friend (female) translates very well.
You say 'su amigo.' masculine. "su amiga", feminine.
She talked with her friend
More polite:Quisiera ser su / tu / vuestro (a) amigo (a).Also possible, but more direct:Quiero ser su / tu / vuestro (a) amigo (a).
SU means WITH
"How is your friend Maria?" is an English equivalent of the Spanish phrase ¿Cómo está su amiga María? The question models a rare instance where English and Spanish sentence structures resemble one another. The pronunciation will be "KO-mo ey-STA soo a-MEE-ga ma-REE-a" in Uruguayan Spanish.
His as of his pants '' su pantalon''
Su autorización - Its okay
You could say "Hola, esta es su amiga hacking su página Facebook." Many computer terms go directly to Spanish from English, especially slang terms like "hacking".
