Definitions and Core Meanings

Preform: To Shape or Create in a Preliminary Form

The term “preform” is a verb meaning “to shape something into an initial or preliminary form.” It refers to preparing or shaping materials before they reach their final state.

For instance, in manufacturing, a preform might be a rough mold or an incomplete object shaped before the final product is ready.

Examples of “Preform” in a Sentence:

• The glass is preformed into a tube before it’s blown into shape.
• The preformed metal structure will later be shaped into a car door.

Perform: To Carry Out an Action or Fulfill a Role

The word “perform” is also a verb, but its meaning is quite different. “Perform” refers to the act of carrying out a task, role, or duty.

This term is often used in settings like theatre, work, and academics to indicate the completion of a task, a job, or an action.

Unlike “preform,” which is about preparation, “perform” is about execution.

Examples of “Perform” in a Sentence:

• The actor performed brilliantly in the play last night.
• Employees are expected to perform their duties responsibly.
