Salve! Ad te advenio. Clarius exprime, quid tibi opus est discere vel scire de hac sententia "Dominus me amat. Dominus me amat quod vitam fili servabam. Sum xeno; Romae sum sextus. Mox liber ero."?
Latin is an ancient language, and your statement translates to: "The master loves me. The master loves me because I saved his son's life. I am a slave; I am in Rome, and I am the sixth. Soon, I will be free."
The lord and I are friends. The master is grateful to me because I had at one time saved his son's life in front of the temple. In Greece my name was Xeno: my Roman name is a common Roman boy’s name. Soon I hope to be free and to be a Roman man.
Are you supposed to translate that? If so, post your translation, and I'll check your work for you.
