Both spellings look correct. Both appear in books and online articles.
Spellcheck may not even flag either one. That’s when doubt creeps in. You may wonder if one is American, the other British, or if one is simply wrong. This confusion is very common, especially for students, writers, and non-native English speakers.
The problem is not your grammar skills. English spelling changes based on region, and many people don’t explain this clearly. Although they look almost the same, they follow different spelling rules.
Once you understand where each spelling is used and why, choosing the right one becomes easy. You’ll write with confidence and stop second-guessing yourself.
1. What Does “Modeled” Mean?

The meaning stays the same everywhere. Only the spelling changes.
2. What Does “Modelled” Mean?
