- Avoid using 'fatty' as a polite adjective for people; use 'overweight' or 'larger' instead.
Common Mistakes
- Using 'fatty' as a polite or clinical term for an overweight person (it's informal/offensive).

FAQ
Frequently Asked Questions
Yes, using 'fatty' as a noun to refer to a person is widely considered rude, derogatory, and insensitive. It should be avoided.
'Fatty' describes something that contains a lot of fat (e.g., fatty bacon). 'Fattening' describes something that causes weight gain (e.g, nuts are fattening). A food can be fatty and fattening, but not always (some fatty foods in moderation may not cause weight gain).
As an adjective in scientific contexts (medicine, chemistry) it is standard and formal (e.g., fatty acid). As a descriptive term for food or people in general writing, it is informal and often inappropriate.
Use person-first, descriptive language like 'a person who is overweight', 'a person with a larger body size', or clinically accurate terms like 'obese' if in a medical context. Avoid slang and labels.
