More bad or worse

Advanced Grammar Course
Today I’m going to explain why we never use the phrase “more better.” I sometimes hear students say this, for example, “My English is getting more better” – but it’s always incorrect.

The reason is this: to compare good things, we use good – better – best:

• Maria’s English is good.
• Ivan’s English is better than Maria’s.
• Sonia’s English is the best in the class.

And to compare bad things, we use bad – worse – worst:

• The first movie was bad.
• The second movie was worse than the first.
• The third movie was the worst of all.

We only use “more” and “most” to compare with adjectives that are longer words – like convenient, interesting, or expensive:

• This book is interesting.
• The documentary is more interesting than the book.
• This is the most interesting class I’ve ever taken.

But we never use “more” or “most” together with better or worse, OK?

Now we can use the word “much” with to add extra emphasis and say that something is a LOT better/worse, not just a little bit better/worse.
