Focusing or Focussing: Which Spelling is Correct?

I still remember the moment when I got stuck on a single word focusing or focussing. I was writing an article late at night, fully focused (or at least I thought I was), when suddenly I paused.  

My fingers hovered over the keyboard, and my confidence disappeared. Which spelling was correct? I felt confused because I had seen both versions used before.

 For a second, I wondered if I had been making this mistake my whole life.

Instead of ignoring it, I decided to handle the issue properly. I stopped writing and started digging deeper. I checked dictionaries, style guides, and even looked at how native English writers use the word in real content.

 That’s when everything became clear. I realized that the confusion wasn’t my fault. English actually allows both spellings, depending on the region.

By understanding the difference, I not only fixed my mistakes but also became more confident in my writing. 

And if you’re facing the same confusion right now, trust me you’re not alone. I’ve been there, and once you understand it, the problem completely disappears.
