Ah, the good old comma splice 💔

Comma splice is one of the most common mistakes I have to correct. Here are some examples of comma splice. 

1️⃣ The figure increased at the beginning of the period, then it decreased gradually by the end.

2️⃣ This research needs to be done urgently, however, it requires a vast amount of money.

3️⃣ Universities give theoretical knowledge, therefore graduates suffer from a lack of real work experience.

This mistake is so common, I wrote a post with a meticulous explanation back in 2021 - and I still send the link to this post to my students to this day. Don't let the name fool you - the mistake is not a comma per se. So, head over to my post to read all about it:

And sometimes students send me screenshots of websites or even English course books with this mistake. Yes, some native speakers make this mistake. And other native speakers write posts and textbook chapters explaining it. As demonstrated in my Telegram post above, sometimes native speakers don't know (or don't care). 

PS: I think "comma splice" is a misnomer. I would call the mistake "conjunction omission." What would you call it?
