Correct spelling, explanation: sense is based on the Latin word sensus, which is the most important basis for the current spelling of the word. When you consider the pronunciation of the word and its structure in related words (sensible), you can clearly see that the spelling sense makes so much sense!

Incorrect spelling, explanation: scense is a misspelling that you should avoid because not only is it not correct, but also it looks like it’s a derivative of scent, instead of being related to the correct word – sense. If you’re unsure, try writing down the related word to see which spelling seems most proper.
