Incorrect belief: Fulfil is wrong because fulfill has two l letters.
Correct understanding: Both spellings are correct. Fulfill is standard in American English, while fulfil is standard in British English.
Mistake 2: Mixing American and British Spelling

For consistency, choose one style:

The correct present participle is fulfilling, with two l letters.
Incorrect: She is fulfiling her responsibilities.

This rule applies to both American and British English.
Mistake 4: Writing Fulfiled Instead of Fulfilled
The correct past-tense form is fulfilled, with two l letters before the e.

Mistake 5: Forgetting the Meaning of the Word
