Performed and preformed are two different words with different meanings, even though they look and sound quite similar.
Performed is the past tense and past participle of perform, meaning to carry out an action, do a task, or present something such as a song or play.
Preformed means made or shaped in advance, before it is needed or used.
For example, “The surgeon performed the operation” means the surgeon carried out the operation. In contrast, “The doctor used a preformed medical device” means the device had already been shaped or made for a particular purpose.
Understanding the difference is especially important in academic, medical, technical, and everyday writing because changing one word can completely change the meaning of a sentence.
