When To Use

Spelling tips for sincerely

The word sincerely is hard to spell because many often miss the second e, as in sincerly, or they include it in the wrong place, as in sincerley. Also, sometimes people may be confused about whether and where the s and c go, as in sinserely or cinserely. How to spell sincerely: The easiest way to remember how to spell sincerely is to start with the adjective sincere. This helps you include the second e in the right place, as sincer would be pronounced quite differently than sincere. Then, you turn sincere into an adverb by adding the typical adverb-forming suffix -ly, resulting in sincerely. To help you remember that sincerely has an s and then a c, keep in mind the phrase "sincere scout." Scout uses an s followed by a c, just like sincere.
