Why Is There Confusion over the Plural of Person?

There is confusion because person typically has an irregular way of forming its plural. It's possible to write persons, but this is only acceptable when written as part of a law or a ruling. For example:

Persons of interest
Missing persons

There is no such word as peoples. People denotes an unspecified number of more than one person.

Beware

Don't Use an Apostrophe to Form a Plural

Adding 's is never an option when forming the plural of a noun. Despite this simple rule, inexperienced writers often feel compelled to add an apostrophe, especially when the noun ends with a vowel (e.g., piano, tomato, emu). For example:

Mango's are low in calories.
Mangoes are low in calories.
