“Families” is the correct plural spelling of “family,” while “familys” is incorrect. Use “families” when referring to two or more family groups.
Confused about families or familys? You’re not alone. This is a common spelling mistake because it may seem natural to simply add -s to “family.” However, standard English follows a different rule: when a noun ends in a consonant + y, the y changes to i and -es is added. That gives us family → families.
So, if you are talking about more than one family, families is always the correct choice. For example, “Several families attended the festival” is correct, while “Several familys attended the festival” is incorrect.
The difference is small, but using the wrong spelling can make your writing look careless or confusing. Whether you are writing a school assignment, email, website content, social media post, or professional document, knowing the correct plural form helps you write with confidence.
It is also important to remember that families is the standard spelling in both American and British English. There is no regional spelling difference between the two. The word can refer to multiple household groups, related groups of people, or families considered as a collective group.
In this guide, you’ll learn exactly why “families” is correct and “familys” is wrong, how the plural spelling rule works, and how to use families naturally in sentences. You’ll also see clear examples and common mistakes so you can remember the spelling easily.
The simple rule to remember is: family → families, not familys.

The Origin of Families
The word family has a long history. It comes from Latin familia, which referred to a household or group connected to a home.
The word later entered English through French and developed into the modern form family.
The plural form follows an old English spelling rule. When a word ends in a consonant followed by y, the final y normally changes to i before -es is added.
That gives us:
family + es → families
This spelling pattern is not unique to family. It appears in many common English words.
For example:
- lady → ladies
- library → libraries
- company → companies
- activity → activities
The spelling familys does not follow this standard plural rule.
British English vs American English Spelling
