How to spell NECCESERILY correctly?

"Necceserily" is a common misspelling of the word "necessarily". To correct the spelling, one can try breaking the word into parts and pronouncing each syllable separately (ne-ces-sa-ri-ly) or remembering the phrase "one collar, two sleeves, and two socks" which contains all the double letters in "necessarily". Another option is to use autocorrect or a spell-check tool.
