Excelerate or Accelerate: Which Spelling Is Correct?

If you are wondering whether the correct spelling is excelerate or accelerate, the standard English word is accelerate. Excelerate is generally a misspelling of accelerate when the intended meaning is to become faster, make something faster, or increase the rate of progress.

Accelerate is a common verb used in everyday, academic, scientific, business, and technical English. It can describe physical speed, growth, development, progress, or a process that becomes faster. Learning the correct spelling is important because excelerate may look reasonable at first, especially because English has words such as excel and excellence that begin with similar letters.

Quick Answer

Accelerate is the correct spelling. It means to become faster, make something faster, or cause a process to happen more quickly. Excelerate is generally an incorrect spelling when you mean accelerate. Remember: accelerate contains accel, not excel.

Why People Confuse It

The confusion mainly comes from pronunciation and familiar words beginning with exce-.

For example:

• excel
• excellent
• excellence

Because accelerate can sound somewhat similar when spoken quickly, some people mistakenly spell it excelerate.

However, the correct spelling is:

accelerate

The word begins with:

accel-

not:

excel-

Another reason for the confusion is that accelerate is pronounced with a sound that can make the first part difficult to identify for some English learners.

Excelerate is generally an incorrect spelling when it is intended as the standard English verb accelerate.

For example:

• The economy may excelerate next year.

Correct:

• The car began to accelerate.
• We need to accelerate the project.
• The economy may accelerate next year.

If you mean to describe something becoming faster or causing something to happen faster, use accelerate.

As a verb, accelerate can mean:

• to become faster

• to cause progress or development to happen more quickly
