Questions & Answers about Mia sorella vive a Londra.
Why does this sentence use a instead of in for "in London"?
In English, we say "in London", but Italian uses the preposition a for cities and towns. You use a whether you are living in the city or traveling to it. The preposition in is saved for larger areas like countries, regions, and big islands (for example, in Inghilterra for "in England").
Why isn't it la mia sorella? Don't Italian possessive words usually need "the" before them?
Where does the word vive come from?
It is the "he/she/it" form of the regular verb vivere (to live). Because "my sister" counts as "she" (third-person singular), we drop the -ere ending from the dictionary form and add -e, giving us vive.
