Excel or Accel: What is the correct Spelling?

Let’s clear up the confusion once and for all.

Excel or Accel – Which Is Correct?

The correct spelling for the verb meaning “to do well or surpass others” is excel, not accel.

Excel comes from the Latin excellere, meaning “to rise or surpass.” It’s the standard term in English when talking about achievement or outstanding performance.

Example:
“I want to excel in academics and develop strong leadership skills.”

On the other hand, accel is not a formal English verb. It’s actually an abbreviation for accelerate, which means “to increase speed.” You’ll find accel in automotive discussions, tech jargon, or gaming slang but it’s not correct in professional writing.

Example:
“This sports car has an incredible accel speed from 0 to 60 mph.”

So remember: Use excel for achievement, and accel as shorthand for acceleration but never interchange them.

Here’s the fundamental difference:

• Excel = To do extremely well, outperform, or surpass others.
