Why is having a first name and surname important?

Today, scenarios are changing and many women are also opting to keep the same surname as they had earlier, prior to their marriage. Both first name and surname are a part of a person's identity. The first name and surname are therefore connected to each other.

Should first and last name be separate fields?

As a UX Designer, when designing forms such as the signup form, you should ask yourself: Is it necessary to have separate fields for first and last name? Most of the time, it's not necessary. In fact, it might be better to merge these fields into one, as people are more likely to have the same first and last name.

Why are surnames written first?

The last name (surname) represents the name of the family to which the child is born (Tendulkar). This approach works well for both boys and girls — as, after all, the family is the smallest unit of the society. Earlier, women who married changed their last names to the family names of their husbands.

Why are last names more formal?

Because when you become friend with a person, you usually start to refer to them by their first name (or nickname for it) which is more personal than the last name.
