This wasn’t an error I came across, but a question I had for myself. Naturally, I had to explore it.

While continuous and continual are fairly similar — they both roughly mean without interruption, its the finer distinctions that separate them.

Continual is frequent events but with intervals in between.

Continuous can refer to space and time and is used more frequently.

Word Confusions…

…started as my way of dealing with a professional frustration with properly spelled words that were out of context in manuscripts I was editing as well as books I was reviewing. It evolved into a sharing of information with y’all. I’m hoping you’ll share with us words that have been a bête noir for you from either end. Consider sharing this Word Confusion with friends by tweeting it.
