Tua vestimenta.
Tua pecunia.
Soror bona tua
Tuus amicus/tua amica.
"Forever your beautiful sister" in English is Per sempre tua sorella bella in Italian and In perpetuum tua soror pulcherrima in Latin.
Gloria tua - your glory Gloriae tuae - your glories/ of your glory
"Your smile is pretty in Latin." Just kidding! The Latin translation is Tua risu est pulchellus.
Tuus, tua, tuum (depending on whether what is yours is masculine, feminine or neuter)
Mater tua is the Latin equivalent of 'your mother'. In the word by word translation, the noun 'mater' means 'mother'. The possessive adjective 'tua' means 'your'.
La Tua Cantante I think that's how it's spelt It means that Bellas blood 'sings' to Edward. Hopefully you know what I mean. It's also explained on page 490 of New Moon in the book La tua cantante is Italian for "your singer" tua is the feminine form of the English word 'you' and cantante is like the Spanish 'cantar' and the Latin 'canto' meaning 'sing'
It means "where." For example, "ubi tua mater?" "Where is your mother?"
