The word “families” also comes from the English language and refers to the people connected with each other. That’s why most people often confuse this word with “family.”But “families” is a plural form of family and comes in a collective noun. Families refer to the group of people who belong to a variety of hierarchy of relation but live in different houses. For example, there is a family of James and another family of a different person named Stephen. So for these two groups of people, we will use the term “families .”These groups of people are separately known as a family, but collectively we call these families.
