Hey there kiddo, have you ever heard someone use special words when they talk to a teacher or a grown-up? Those words are called "forms of address." When we use forms of address, we use certain titles and names to show respect to the person we are speaking to.
Let's say you are talking to your teacher, Ms. Smith. Instead of just saying "Hey you!" you might use the form of address "Ms. Smith." This shows that you respect her and her authority as your teacher.
There are many different forms of address that we can use. For example, we might use "Mr." or "Ms." for adults we don't know very well or in more formal situations. We might use "Auntie" or "Uncle" for family members, and we might use "Doctor" or "Professor" for people with certain job titles.
Sometimes, people might have multiple forms of address depending on the situation. For example, your dad might be called "Dad" at home, but at work, his employees might call him "Mr. Johnson" to show respect.
Using forms of address is a way of being polite and respectful to the people we talk to. It helps us show that we understand different social situations and know how to behave appropriately.
