Usage
What is a basic definition of worst? Worst describes something as being bad in the highest degree possible. Worst is also used to mean a thing that is the baddest possible and to mean something done in the baddest manner possible. Worst has several other senses as an adjective, adverb, noun, and verb. Worst is a superlative of the word bad. Simply put, worst describes something as being the baddest out of a group, category, list, and the like. This can mean something is most evil, is least skilled, is most unsatisfactory, is of the poorest quality, or is most unpleasant. What someone thinks of as the worst something depends on what they’re judging that thing on. As with bad, worst is often a person’s opinion.
- Real-life examples: Everybody has a movie that they think is the worst (poorest quality or most unpleasant to watch) movie ever made. The worst student in a class could be the one who scores the lowest on tests or the one who misbehaves the most. A runner who records the worst time in a race is the one who ran the slowest. The worst person you know might be the one with the most unpleasant personality or who treats you the most poorly.

Etymology
Origin of worst
First recorded before 900; Middle English worste (adjective, adverb, and noun), Old English wur(re)sta, wyr(re)st, wer(re)sta (adjective and adverb); cognate with Old Norse verstr; see worse, -est 1
Explanation
The adjective worst describes the thing that is the least good, like this awful pizza, the worst we've ever had in our lives. Worst means "the least favorable outcome." You may have heard the saying "hope for the best but expect the worst." Well, it you get the worst, you know there is nothing more bad than that. If you are at your worst, you have never before felt or performed this poorly. Don't confuse worst with worse, which compares only two things. Your cold might be worse than your brother's but dad's is the worst of all.
