Vosté is a very polite form of address for a single person. It is used with the third-person singular form of the verb. (Compare the polite usage of usted in Spanish.) Traditionally it was only used with judges, doctors, and so on, with vós being used in most polite situations, for example with elderly people, and tu being used in informal situations. Nowadays, tu is the most common form, even in formal contexts, and vosté is becoming more common than vós because of contact with Spanish. In Catalonia, this word is usually spelled vostè, since it has /ɛ/ instead of /e/.
