Who or That?

English tip:

He is the man that saved my daughter.
He is the man who saved my daughter.

Which is right?

There are two camps of thoughts.
One says we can only use "that" to refer to things and "who" is used for people.
Another says we can use "that" to refer to both people and things.

As a safety rule, why don’t we stick to the first camp, i.e. using "that" for things, especially during the examinations. Using "that" to refer to people is unfashionable and rude to some.

Have you been using "that" because you are unsure when to use "who" or "whom" and try to avoid it by using "that"?

In the next tip, we will tackle "who" vs "whom."
