What are the comparative and superlative degree of ill?

The word "ill" is an adjective that describes a state of being unwell. It doesn't have comparative or superlative forms in the traditional sense.

Here's why:

* Illness is a state, not a degree: Illness is a condition, not something that can be more or less of. You're either ill or you're not.

* We use other words for degrees of illness: To express different levels of illness, we use other words like:

* Slightly unwell

* Moderately ill

* Seriously ill

* Critically ill

Instead of trying to find comparative and superlative forms of "ill," focus on using more specific language to describe the severity of someone's illness.
