'Thirteenth' is used to describe something that comes after the number twelve. For example, if there are 12 people in a group and another person joins, then there are 13 people in the group. So, the new person is the thirteenth person in the group. You can also use 'thirteenth' to describe the 13th day of the month or the 13th floor of a building. It is important to remember that 'thirteenth' only applies to the number 13 and not to any other number.
