Simple Background

The base verb is “swear.”

It has three main forms:

• Present: swear
• Past: swore
• Past participle: sworn

These forms are part of what we call an irregular verb, which means it does not follow the normal “ ed” pattern (like walk → walked).

Instead, it changes like this:

• swear → swore → sworn

This is why many learners feel confused.
