What Does “Worse Case” Mean?

Technically, “worse case” is not grammatically correct in standard English when used alone.

It needs a comparison to make sense.

This confusion mainly comes from mixing up comparative vs superlative forms.

Bad → Worse → Worst

People often:

Hear both words used in similar contexts
Assume they are interchangeable
Forget the grammar rule behind them

👉 Think of it like this:

Worse = comparing two things
Worst = the extreme or final level
