## Prompt

Spell 'necessary.'

## Response

**Necessary** is spelled: **n-e-c-e-s-s-a-r-y** — one **c** and a double **s**, ending with **-ary**.[2](https://www.bachelorprint.com/spelling-mistakes/necessary-or-neccessary/)  

A common mistake is *neccessary* (with double c), which is always incorrect.[2](https://www.bachelorprint.com/spelling-mistakes/necessary-or-neccessary/)  

## Quick way to remember

**Mnemonic:** *One c*ollar and *two s*ocks are ne**c**e**ss**ary — so the word has **1 C** and **2 S’s**.[2](https://www.bachelorprint.com/spelling-mistakes/necessary-or-neccessary/)
