# Coeficient vs. Coefficient: Mastering the Correct Spelling

Edited by Aimie Carlson || By Harlon Moss || Published on March 14, 2024
"Coeficient" is an incorrect spelling, while "coefficient" is correct, referring to a numerical or constant factor in a mathematical expression.

## Which is correct: Coeficient or Coefficient

How to spell Coefficient?

## Key Differences

Remember that formulas often require precision, and "coefficient" requires a double "f" for accuracy.
Write "coefficient" several times or use flashcards with the word to reinforce the correct spelling visually.
"Co" as in together, and "efficient" with double "f" to work efficiently in equations.
Think of "coefficient" as being "co-efficient," where "co-" implies together and "efficient" suggests effectiveness, even though it's not the actual etymology.
Break it down to "co-ef-fi-cient" when pronouncing it to remember the spelling.
