Which is correct: Coeficient or Coefficient

How to spell Coefficient?

Coeficient is Incorrect

Coefficient is Correct


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.
