English has many words that are spelled differently and have different meanings, but which, when spoken, sound similar or even exactly the same. These words are called homophones, and they can make life confusing for someone who isn’t familiar with them. To make matters even worse, inexperienced writers are prone to misusing these words, which only adds to the confusion. Fortunately, there is any easy trick to figuring out whether gist or jist should be used in any situation.
The word gist originated from early 18th century: from Old French, third person singular present tense of gesir ‘to lie’, from Latin jacere . The Anglo-French legal phrase cest action gist ‘this action lies’ denoted that there were sufficient grounds to proceed; gist was adopted into English denoting the grounds themselves (sense 2).

If you can’t decide whether to use jist vs. gist, remember that gist is a good word for a summary or main point, and jist is just wrong.
