Understanding the Basics

Definition of Perform

Perform refers to the action of carrying out, executing, or doing something. When we perform, we are engaging in an activity or presenting an artistic display to an audience. For instance:

  • Actors perform in a play.
  • Musicians perform at a concert.

Definition of Preform

On the other hand, preform is a less common word indicating the action of shaping or fashioning something in advance. We use preform when referring to the preparation of materials or components before they undergo a final manufacturing process. For example:

  • Factories preform plastic bottles before filling them with beverages.
  • Manufacturers perform metal parts prior to assembly.

Grammatical Functions

Perform in Sentences

Perform acts as a verb that indicates the execution of an action or the carrying out of a task. When we use perform in sentences, it typically requires a subject that can carry out the action and, often, an object that receives the action.

  • Subject | Verb | Object
  • Jane | will perform | a song tonight.

We may also use “perform” in an intransitive manner, where the sentence does not need an object.

  • Subject | Verb
  • The magician | performed.

Preform in Sentences

Preform, on the other hand, is a less commonly used verb that means to shape or form something before another process. In sentences, preform also serves as a verb, illustrating the preparation or initial shaping of an object.

  • Subject | Verb | Object
  • The factory | preforms | plastic bottles before filling.

Preform can be transitive, requiring a direct object to complete its meaning.

  • Subject | Verb | Direct Object
  • They | will preform | the metal.

Common Usage

When to Use Perform

Perform is a verb that we use when referring to the action of carrying out, executing, or doing something. It’s particularly common in contexts where someone is presenting or engaging in a specific activity. For example:

    • The musician will perform live at the concert tonight.
  • In General Tasks: It can refer to any individual completing a task or duty.
    • The surgeon is ready to perform the procedure.

When to Use Preform

On the other hand, preform is a lesser-known word that we use mainly in manufacturing and production. It refers to shaping or forming something beforehand. Here’s how we use it:

  • In Manufacturing: When a material is shaped before being assembled or finished.
    • The factory preforms plastic bottles before filling them.
  • In Preparation: It can also indicate preparing certain materials or elements prior to a final process.
