Common Mistakes People Make
1. Thinking One Spelling Is Wrong
Many learners believe that only one spelling is correct.
This is not true.
Both spellings are accepted English.
✔ Correct:

2. Mixing British and American Spellings
Example:
- The event was organised and carefully analyzed.
This mixes British and American spelling styles.
It is usually better to stay with one style.
