Worst

Weather gets the comparitive degree - "The weather is getting worse". 'Worst' is appropriate if you say, frex, "The weather is at its worst".

The second sentence isn't correct. It's a sentence fragment, and screams for a verb to help it along. The use of 'worst' is correct - "Our ten best and ten worst clients came by the office today". To use 'worse', then it'd need to be a slightly more awkward sentence like "Ten of our better and ten of our worse clients paid their accounts last week".

How can you say the second sentence isn't correct?
- Who are coming to the meeting?
- The ten best clients and the ten worst clients.

It's still a sentence fragment. Fragments are correct in many, many cases, but a fragment isn't technically a sentence.

Yes, the second "sentence" may be a fragment, but that isn't what Ted really wanted to know.

Ted, "worst" is the opposite of "best," so despite the fragmentary nature of your second example, the usage of "worst" is correct. They are both superlatives (think about other similar words that end in -est, such as "prettiest" and "highest").

But when describing something that has gotten more undesirable in some way, the correct word is "worse."

Examples:

"My son used to just steal beer from the refrigerator, but now he has become hooked on drugs. I have had the worst time dealing with him. He has gone from bad to worse."

"My boss insults customers, golfs on work time, and lies on his expense account. But worst of all, he cooks the books. I have never had a worse boss."

It may help to experimentally substitute "better" and "best" into the sentence to see which makes more sense. If "better" sounds better, then you would use "worse;" if "best" sounds like the right fit, then use "worst."

I have a question. Now if I were to refer to an evil world leader, more specifically the most evil, would I say the 'best' evil leader or would it be the 'worst' evil leader?

Is this sentence correct? "it will just make the situation alot worst"
