Answer:
formally and informally.
Explanation:
<u>In Spanish, we distinguish two ways of addressing someone</u>: formally and informally.
When talking to a friend, we use the pronoun <em>tú</em>. We must also use the <u>verb conjugated in the second person plural</u>, while if we refer to a group of two or more friends, we use the pronoun <em>vosotros</em>, and the <u>second person plural form for the verb</u>. This is informal address.
However, when we talk to a teacher, an elder, a boss or whomever we want to be respectful towards, we use the pronoun <em>usted</em>, which uses the <u>third person singular form of the verb</u>, while if there are two or more of our interlocutors, we use <em>ustedes</em>, and the <u>third person plural form of the verb.</u> This is a way to address somebody formally.
