Correct spelling, explanation: sense is a word based on the Latin sensus, which means both the feeling and the thought. Of course, as sense adapted to English it has lost the Latin -us ending, and took an e at the end instead, as many Latin-based words do. This way, the core structure of the word remained the same, while, at the same time, allowing the word to fit well into English vocabulary.

Incorrect spelling, explanation: the word scense is an incorrect spelling variant of the word sense. The predecessor of the word sense, which is Latin sensus, does not support adding the letter c, as it’s not necessary here. If you’re still unsure about the spelling of sense in the future, try imagining connected words such as sensible, and decide accordingly.
